Ah hold on. More information.

If I build a gcc with --disable-bootstrap, the resulting compiler cannot build
an empty C program even:

% /home/vext01/research/warmup_experiment/work/gcc-inst/bin/zgcc /tmp/a.c
/usr/bin/ld: /tmp//ccGIx4CB.o: relocation R_X86_64_32 against `a local symbol'
can not be used when making a shared object; recompile with -fPIC
/tmp//ccGIx4CB.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status


If I add -fPIC, the program compiles, but I do no expect to have to tack on
-fPIC for such a program. This is probably why the second stage gcc build is
failing too. I don't think we should have to pass down -fPIC to the second
stage, no?

Thanks
