I just built and compiled gcc v6.2.0 and it compiles seabios fine.
So, this looks like a debian bug, and I think it should be filed

I don't see where pic (position independent code) is related. My
guess is that it just causes random code changes which then doesn't
tickle the underlying issue.
Does adding '-fno-pie' help?
