Get rid of some CFLAGS for glibc 2.2

[Andreas Jaeger <aj at suse dot de>]

Some of glibc's Makefiles contain flags to disable warning messages
for some files.  But since the introduction of those flags, the files
have been changed and sometimes the disabling is not necessary
anymore.

I checked if those still are needed and append a patch for those which
can be removed (tested with gcc 2.95.2 and egcs 1.1.2).  I've also
patched regex.c to remove some really unused variables.

What's the philosophy about -Wno-uninitialized?  gcc 2.95.2 seems to
give less warnings than egcs.  Some further flags can be removed if we
would use gcc 2.95.2 as reference.

	* stdio-common/Makefile (CFLAGS-_itoa.c): The code has been
	fixed, we don't need to disable the warnings anymore, remove them.
	* elf/Makefile (CFLAGS-dl-load.c): Likewise.

	* posix/Makefile (CFLAGS-regex.c): Remove not needed warning
	flag.

	* posix/regex.c (regex_compile): Remove unused variables.
