Sorry to burst your bubble but this doesn't work in the real world,
where "real world" is defined as 'hppa-linux-gcc -o hello hello.c'

In fact this new linker ends up marking basically everything as
potentially PIC, creating unnecessary import stubs for most functions
in libc.a, and *not* actually switching the relocations to point to
import stubs in the case where I am actually calling PIC in libgcc.a.

Oh and it segfaults on undefined weak symbols though that's easily
fixed.

I'm not even sure where to start fixing this.  I guess I'll try to
find something else to do today :(
