This is actually due to the --whole-archive that perl is using which it
really doesn't need anymore and should be fixed.

I can provide you stub routines for the _Qp* stuff today. Just anything which
tries to call them with the current compiler will break (which is what I'm 
still working on).

Backing out the -msoft-quad on libgcc will break almost anything which uses
floating point in some way. Thats the whole reason awk/etc weren't working
before so simply going back to that point isn't a good solution either.

I'll check in the Qp stubs later so at least things link (the parts of libgcc
that call this stuff are very rarely touched but I'll test perl with it).
