We should always include symbol name when reporting relocations
error to simplify debugging of these issues. Without symbol names
users have to manually investigate which of the libraries contain
invalid relocations which can be cumbersome when linking multiple
libraries.

Copy relocations are relocations to copy data from DSOs to
executable's .bss segment at runtime. It doesn't make sense to
create such relocations for zero-sized symbols.
GNU linkers don't agree with each other. ld rejects such
relocation/symbol pair. gold don't reject that but do not create
copy relocations as well. I took the former approach because
I don't think the latter is what user wants.
