Being execution errors, gcc.log doesn't tell anything besides abort being
called.
Judging from the patch, the failing tests and the tested target-list (in
particular, their difference to cris-elf), maybe libcalls aren't handled
properly. The previously pushed (and reverted) version caused the same (or a
very similar set of) regressions. Will look closer.
