Well, that's something to fix in the LTO code.

We have been doing that for a number of releases on Fedora. Seems to
work fine.

Well, that's something to fix in gold.

What's wrong with adding

       CFLAGS=-fno-lto LDFLAGS=-Wl,-fuse-ld=bfd

to the end of your configure line? That should be option enough...

The thing is that LTO is actually kinda important for us, since we
link so much stuff over and over again into many binaries.
