[Patch] Fix PRI_MACROS_BROKEN undef warnings.

[Steve Ellcey]

Here is another undefined macro warning fix.  PRI_MACROS_BROKEN is only
used in loadmsgcat.c in the intl directory.  It is never set anywhere in
glibc sources but binutils and gcc use a intl directory that I believe is
derived from the glibc one.  The configure scripts of these products set
PRI_MACROS_BROKEN, but the intl sources in them don't appear to have been
updated from glibc since 2003.

So, if we care about keeping something that is usable with GCC/binutils
this patch seems like the best fix but if we don't care about staying in
sync with the intl directory of GCC or binutils we could just remove
PRI_MACROS_BROKEN completely or even remove the entire section of code
that sets the various PRI* macros since we know that glibc itself has the
correct definitions.

The m4 macro that binutils and GCC use to set PRI_MACROS_BROKEN mentions
AIX 4.3.3 as a platform where the macros are defined as non-string values.
There are already a number differences between intl in glibc and the one
in GCC and binutils.

Tested on mips-mti-linux-gnu with no difference in the object files
generated.
