One minor issue that I've noticed is that the patch generates a lot of
empty *debugobj* files in $TMPDIR, e.g.:
% echo 'int main(){}' | g++ -flto -o /dev/null-x c++ -
% ls -l $TMPDIR
total 0

-rw-------. 1 trippels trippels 0 Sep 6 12:11 ccXzvE4udebugobjtem
The new patch builds LLVM fine with "-flto -g".
