Remaining content of x-fragments

[Zack Weinberg]

Appended is a report on the remaining content of the x-fragments.  For
each variable set there, for each value it's set to, the report lists
all the files that set it to that value.

It appears to me that most of these variables properly belong to the
t-fragments.  Of the variables set:

X_CFLAGS, RANLIB, RANLIB_TEST, INSTALL, CC, SHELL, BOOT_LDFLAGS are
definitely host configuration.

STMP_FIXPROTO, FIXPROTO_DEFINES, SYSTEM_HEADER_DIR, LIB2FUNCS_EXTRA,
EXTRA_PARTS are definitely target configuration.

OTHER_FIXINCLUDES_DIRS, LIBGCC2_INCLUDES, LIMITS_H_TEST, USE_COLLECT2
I'm not sure about.

Since fixincludes and fixproto are both disabled in a cross
configuration, setting variables that control them in an x-fragment
instead of a t-fragment is harmless.  However, some of the other
settings are not so harmless; SYSTEM_HEADER_DIR, LIB2FUNCS_EXTRA,
EXTRA_PARTS, and USE_COLLECT2 all affect the compiler itself.
