I configured the build with
../work/configure --prefix=/opt/gcc/gcc4.7w
--enable-languages=c,c++,fortran,objc,obj-c++,java,lto --with-gmp=/opt/sw64
--with-libiconv-prefix=/opt/sw64 --with-system-zlib --with-cloog=/opt/sw64
--enable-cloog-backend=isl --enable-lto
A nonparallel make gives
# If this is the top-level multilib, build all the other
# multilibs.
/bin/sh ../../../../work/libgcc/../mkinstalldirs ../../.././gcc/i386
for file in libgcc_s.1.dylib libgcc_ext.10.4.dylib libgcc_ext.10.5.dylib; do
\
rm -f ../../.././gcc/i386/$file; \
ln -s ../$file ../../.././gcc/i386/; \
done
rm -f ../../.././gcc/i386/libgcc_s_x86_64.1.dylib
ln -s libgcc_s.1.dylib \
../../.././gcc/i386/libgcc_s_x86_64.1.dylib
rm -f ../../.././gcc/i386/libgcc_s_ppc64.1.dylib <-- ppc64 seems
quite suspicious here
ln -s libgcc_s.1.dylib \
../../.././gcc/i386/libgcc_s_ppc64.1.dylib
# If the gcc directory specifies which extra parts to
# build for this target, and the libgcc configuration also
# specifies, make sure they match. This can be removed
# when the gcc directory no longer holds libgcc configuration;
# it is useful when migrating a target.
Configuration mismatch!
Extra parts from gcc directory: crtfastmath.o crtprec32.o crtprec64.o
crtprec80.o
Extra parts from libgcc: crt3.o
