Unwrap symbols for debug information
Fixes issues with dwz multi-file (-m) and ld's -wrap option.
Symbols referenced from DWARF debug info in a separate file, eg. to
specify low and high pc, must use the real symbol. The DWARF info
is specifying attributes of the real function, not one interposed
with --wrap.

* linker.c (unwrap_hash_lookup): New function.
* elf-bfd (RELOC_FOR_GLOBAL_SYMBOL): Call unwrap_hash_lookup.
