Some PIC code is finding its way into the static binary. This is also
the cause of bug#251. The function crashing is called:

_GLOBAL_sub_I_eh_globals.cc

which is one of a group of functions whose name starts "_GLOBAL_sub_I"
and they all contain PIC code.

I'm not sure if these functions are compiler generated or come from
the static standard libraries, if the latter, it could indicate a build
problem in libstdc++.
