I just got on x86_64 with multi-libs:

configure: loading cache .././config.cache
configure: error: `LDFLAGS' was not set in the previous run
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm .././config.cache' and start o
ver
make[2]: Entering directory `/builds/gcc/misc/gcc'
if test -f stage_last ; then \
  LAST=`cat stage_last`; rm $LAST; make LANGUAGES="c gcov gcov-dump ada c++ f77 
java objc treelang" BOOT_CFLAGS="-g -O2" $LAST; \
else \
  make LANGUAGES="c gcov gcov-dump ada c++ f77 java objc treelang" BOOT_CFLAGS="
-g -O2" stage1_build; \
fi
make[1]: *** [configure-fastjar] Error 1
