PowerPC gold assertion on missing global entry stub
Global entry stubs are used on ELFv2 to provide addresses for
functions not defined in a non-PIC executable but whose address is
taken, in much the same way as PLT stub code is used on other
targets to provide function addresses. We don't want to insert a
global entry stub just because (bogus) debug info refers to the
address of a non-local function, but we also don't want gold to die.
* powerpc.cc (Target_powerpc::Relocate::relocate): Don't assert
on missing global entry stub due to bogus debug info.
