- Subject: Clean up i386/gnu.h
Now that gnu-user*.h and linux*.h config headers have more or less the
proper contents, the next stage in stopping non-Linux-kernel-based
targets from using linux*.h is to get the correct contents into the
headers for the non-Linux-kernel-based targets. This patch does so
for i386/gnu.h. GNU_USER_LINK_EMULATION is defined (to the same value
as in i386/linux.h, so just duplicating that definition until this
target stops using i386/linux.h). CPP_SPEC, duplicating the
i386/gnu-user.h definition, is removed, as is CC1_SPEC (missing
-profile support from the gnu-user version, which should be there
judging by -profile support in other specs). ENDFILE_SPEC is also
removed; the gnu-user version has additional support for crtfastmath.o
and crtprec*.o and since libgcc/config.host indicates those files get
built for GNU/Hurd, the gnu-user spec that uses those files should be
used for GNU/Hurd.
Tested building cc1 and xgcc for cross to i686-gnu. OK to commit?

* config/i386/gnu.h (GNU_USER_LINK_EMULATION): Define.
