unit-at-a-time fixes

[Andreas Jaeger]

With GCC 3.4 and also the hammer-branch of GCC 3.3, unit-at-a-time
compilation is enabled and rearranges the output order of functions.
This is not desirable in some cases.

Here's the patch that we're currently using at SuSE.  Ok to commit?

2003-11-30  Andreas Jaeger  <aj@suse.de>

	* csu/Makefile (CFLAGS-initfini.s): Add -fno-unit-at-a-time.
	* linuxthreads/sysdeps/unix/sysv/linux/x86_64/Makefile
	(CFLAGS-pt-initfini.s): Likewise.
	* locale/Makefile (CFLAGS-loadlocale.c): Likewise.

For linuxthreads:
	* Makefile (CFLAGS-tst-cancel.c): Add -fno-unit-at-a-time.
	(CFLAGS-pt-initfini.s): Likewise.

For nptl:
	* Makefile (CFLAGS-pt-initfini.s): Add -fno-unit-at-a-time.
