Paul E. Murphy 3c46d8f511 cmd/link: load external ELF PPC64 objects which set st_other=1
This indicates the symbol does not use or preserve the TOC pointer in
R2. Likewise, it does not have a distinct local entry point. This
happens when gcc compiles an object with -mcpu=power10.

Recycle the SymLocalentry field of a text symbol to pass through this
hint as the bogus value 1 (A valid offset must be a multiple of 4
bytes), and update the usage to check and generate errors further into
the linking process. This matches the behavior of st_other as used by
ELFv2.
