well static pie is broken now, i care about that more.
we don't know yet how capability relocs will work with
static linking and ifuncs.
but the main problem with this idea is that i have
to copy a large part of the elf reloc code and hack
it apart to do static pie relocation (and that code
is not a nice piece of code in the first place).
