If we can identify these ELF objects by looking in the ELF header,
why would we want to make this all a configure option that's
disabled by default?

I think we should just have support for these binaries enabled
always. Otherwise it will bitrot because nobody compiles it.

We are relying on a pre-existing CONFIG_USE_FDPIC, which is currently
never defined. This was introduced by commit 1af02e83 back in 2011,
and indeed if you try to build QEMU with CONFIG_USE_FDPIC, the build fails 
because elf_is_fdpic() is not defined.

We tried to conform to this existing support, but maybe it's already bit-rotten?
Do you suggest removing CONFIG_USE_FDPIC?
