picflag.m4 isn't used only in binutils, but for several gcc libraries as
well. That's why I'm arguing to use a safe default (-fPIC) if feasible,
rather than adjusting/overriding whenever -fpic breaks. Overrides like
in libgcc/config/s390/t-crtstuff don't seem particularly useful to me,
especially when done with no explanation as I suggested when that patch
went in.
