Final conclusion: We need to resolve to the executables PLT consistently,
even from inside the shared object where the function binds locally. This
is because of references to the function from the executables .rodata section
which we can't relocate (and thus have to point to the executables PLT entry).
Thus, this is a GCC target bug.
__attribute__((visibility("protected"))) void * foo () { return foo; }
needs to return the address of foo via a load from the GOT. HJs patch
isn't correct as this is really a target ABI choice (another ABI may
choose to resolve all references to the functions start address with
the cost of having to put the constants into a .rel.rodata section).
