[patch] ppc64 native target for gcc

[Jack Howarth]

Eric,
   At least for gcc 4.2 on a G5 if I do...

setenv CFLAGS "-O2 -m64 -g"
setenv CPPFLAGS "-O2 -m64 -g"
setenv CXXFLAGS "-O2 -m64 -g"
setenv LDFLAGS "-O2 -m64 -g"
../gcc/configure --prefix=/Users/howarth/work/gcc42 --enable-languages=c,c++ --host=powerpc64-apple-darwin8 --target=powerpc64-apple-darwin8 --disable-multilib
make

...the build fails at...

ranlib libcpp.a

All the source files in intl are compiled with -m64. Any idea why this if failing on MacOS X 10.4.8
with Xcode 2.4.1? Also shouldn't the powerpc64-apple-darwin8 host and target preset -m64 for the 
compiler flags as well?
