macho: resolve special section/segment boundary symbols
Boundary symbols have a special name prefix:
* section$start$segname$sectname
* section$stop$segname$sectname
* segment$start$segname
* segment$stop$segname
and will resolve to either start or end of the respective
section/segment if found.
If not found, we return an error stating we couldn't find the
requested section/segment rather than silently failing and resolving
the address to 0 which seems to be the case with Apple's ld64.
