arm32 __bionic_call_ifunc_resolver: let the compiler handle initialization.
I don't think we need this, and we're not doing it for the equivalent
code in riscv64. So either we do need it, and this will help us find out
quicker and make the corresponding riscv64 change, or we don't need it,
and this is a free cleanup.
