'stack overflow' message for Darwin; host hooks

- Subject: 'stack overflow' message for Darwin; host hooks
This patch does two thing:
1. It establishes a system for host-specific callbacks. The system is
way too elaborate for the trivial purpose in the patch, but I plan
do extend it later to add host-specific ways to detect that we
don't need to do a GC collection right now, and to perform
incremental GC.
2. It fixes an annoying UI issue with GCC on Darwin. Darwin has the
default soft stack limit set to 512k, which can be easily tripped
over; in fact, some tests in the GCC testsuite hit it. Before,
when this happened GCC would print 'Internal error: bus error',
which is an incredibly unhelpful error message; now it prints
'Out of stack memory.' and a message saying how to change the
limit.
Bootstrapped & tested on powerpc-darwin. No new tests fail, and
the following old failures now have a better error message:
FAIL: gcc.c-torture/compile/20001226-1.c, -O2
FAIL: gcc.c-torture/compile/20001226-1.c, -O3 -fomit-frame-pointer
FAIL: gcc.c-torture/compile/20001226-1.c, -O3 -g

+
+Most details about the machine and system on which the compiler is
+actually running are detected by the @command{configure} script. Some
+things are impossible for @command{configure} to detect; these are
+described in two ways, either by macros defined in a file named
+@file{xm-@var{machine}.h} or by hook functions in the file specified
+by the @var{out_host_hook_obj} variable in @file{config.gcc}. (The
+intention is that very few hosts will need a header file but nearly
+every fully supported host will need to override some hooks.)
+
+If you need to define only a few macros, and they have simple
+definitions, consider using the @code{xm_defines} variable in your
+@file{config.gcc} entry instead of creating a host configuration
+header. @xref{System Config}.
