Even the most minimal config fails on my machine:
 gcc_build_dir % ../gcc/configure --disable-multilib --enable-checking
--enable-languages=c,c++
 gcc_build_dir % make -j4

My gcc git clone is clean:
 gcc % git status
# On branch master
nothing to commit (working directory clean)

Can anybody else except Jason reproduce this issue?
