Funny you should mention that.
The appended - completely untested; I'll be running a bootstrap
shortly, but won't be back to check on it till late tonight - patch
rips out all remaining traces of libgcc1. You can still get extra
assembly routines stuck into libgcc.a with LIB1ASMFUNCS, and you don't
have to set LIBGCC1 anymore.
Being rather brutal, it may change behavior on some targets. For
instance, it appears that most ARM targets ask for assembly routines
only when they're cross-compile targets. I do not understand why they
are not needed in a native build. This toggle could be restored if
it's genuinely necessary.
Also, the i370 targets all disabled libgcc.a entirely. This cannot
possibly be correct.
Suggested for mainline only. I have to run out the door, so the
changelog can wait.

-
-Code compiled by GNU CC uses certain runtime support functions
-implicitly. Some of these functions can be compiled successfully with
-GNU CC itself, but a few cannot be. These problem functions are in the
-source file @file{libgcc1.c}; the library made from them is called
-@file{libgcc1.a}.
-
-When you build a native compiler, these functions are compiled with some
-other compiler--the one that you use for bootstrapping GNU CC.
-Presumably it knows how to open code these operations, or else knows how
-to call the run-time emulation facilities that the machine comes with.
-But this approach doesn't work for building a cross-compiler. The
-compiler that you use for building knows about the host system, not the
-target system.
-
-So, when you build a cross-compiler you have to supply a suitable
-library @file{libgcc1.a} that does the job it is expected to do.
-
-To compile @file{libgcc1.c} with the cross-compiler itself does not
-work. The functions in this file are supposed to implement arithmetic
-operations that GNU CC does not know how to open code for your target
-machine. If these functions are compiled with GNU CC itself, they
-will compile into infinite recursion.
-
-On any given target, most of these functions are not needed. If GNU CC
-can open code an arithmetic operation, it will not call these functions
-to perform the operation. It is possible that on your target machine,
-none of these functions is needed. If so, you can supply an empty
-library as @file{libgcc1.a}.
-
-Many targets need library support only for multiplication and division.
-If you are linking with a library that contains functions for
-multiplication and division, you can tell GNU CC to call them directly
-by defining the macros @code{MULSI3_LIBCALL}, and the like. These
-macros need to be defined in the target description macro file. For
-some targets, they are defined already. This may be sufficient to
-avoid the need for libgcc1.a; if so, you can supply an empty library.
-
-Some targets do not have floating point instructions; they need other
-functions in @file{libgcc1.a}, which do floating arithmetic.
-Recent versions of GNU CC have a file which emulates floating point.
-With a certain amount of work, you should be able to construct a
-floating point emulator that can be used as @file{libgcc1.a}. Perhaps
-future versions will contain code to do this automatically and
-conveniently. That depends on whether someone wants to implement it.
-
-Some embedded targets come with all the necessary @file{libgcc1.a}
-routines written in C or assembler. These targets build
-@file{libgcc1.a} automatically and you do not need to do anything
-special for them. Other embedded targets do not need any
-@file{libgcc1.a} routines since all the necessary operations are
-supported by the hardware.
-
-If your target system has another C compiler, you can configure GNU CC
-as a native compiler on that machine, build just @file{libgcc1.a} with
-@samp{make libgcc1.a} on that machine, and use the resulting file with
-the cross-compiler. To do this, execute the following on the target
-machine:
-
-@example
-cd @var{target-build-dir}
-./configure --host=sparc --target=sun3
-make libgcc1.a
-@end example
-
-@noindent
-And then this on the host machine:
-
-@example
-ftp @var{target-machine}
-binary
-cd @var{target-build-dir}
-get libgcc1.a
-quit
-@end example
-
-Another way to provide the functions you need in @file{libgcc1.a} is to
-define the appropriate @code{perform_@dots{}} macros for those
-functions. If these definitions do not use the C arithmetic operators
-that they are meant to implement, you should be able to compile them
-with the cross-compiler you are building. (If these definitions already
-exist for your target file, then you are all set.)
-
-To build @file{libgcc1.a} using the perform macros, use
-@samp{LIBGCC1=libgcc1.a OLDCC=./xgcc} when building the compiler.
-Otherwise, you should place your replacement library under the name
-@file{libgcc1.a} in the directory in which you will build the
-cross-compiler, before you run @code{make}.

-Define this macro to override the type used by the library routines to

-of @code{float} and @code{int}.)
-
-The obvious choice would be @code{float}---but that won't work with

-ask for the value as some other type and then treat it as a @code{float}.
-
-On some systems, no other type will work for this. For these systems,

-the values @code{double} before they are passed.

-@item FLOATIFY (@var{passed-value})
-Define this macro to override the way library routines redesignate a

-Define this macro to override the way the value of a
-@code{float}-returning library routine should be packaged in order to
-return it. These functions are actually declared to return type
-@code{FLOAT_VALUE_TYPE} (normally @code{int}).
-
-These values can't be returned as type @code{float} because traditional
-C compilers would gratuitously convert the value to a @code{double}.
-
-A local variable named @code{intify} is always available when the macro
-@code{INTIFY} is used. It is a union of a @code{float} field named
-@code{f} and a field named @code{i} whose type is
