hm, yes dynamic loading from static linked binaries is not
needed in a static only build, but i think currently we
don't distinguish a static libc.a and a "static only" libc.a

we also need to keep some elf code because static pie still
needs self relocation.

i think if it's easy to rip out the dynamic loading code,
then it makes sense to do so (assuming static pie still works)
and if it's hard then it's ok to fix --disable-shared with
minimal effort and apply the patch.
