Subject: fix profiling on Darwin


This patch:

2003-01-27  Nathan Sidwell  <nathan AT codesourcery DOT com>

	* Makefile.in (LIB2FUNCS_ST): Remove _gcov.
	(LIBGCOV): New variable.
	(libgcc.mk): Add LIBGCOV.
	(LIBGCC_DEPS): Add libgcov.c.
	(libgcov.a): New target.
	(clean): Remove libgcov.a.
	(install-libgcc): Do libgcov too.
	(stage1-start, stage2-start, stage3-start, stage4-start): Deal
	with libgcov.a.
	* libgcc2.c (L_gcov): Move into ...
	* libgcov.c: ... here. New file.
	* mklibgcc.in: Add libgcov rules.
	* gcc.c (LINK_COMMAND_SPEC): Add -lgcov when profiling.

broke profiling on Darwin because Darwin has its own
LINK_COMMAND_SPEC and Nathan didn't update it.  This patch fixes it.

Probably djgpp also needs a similar patch since it also has its own
LINK_COMMAND_SPEC.

Bootstrapped & tested on powerpc-darwin.
