[release-branch.go1.19] cmd/link: fix trampolines breaking DWARF line info
When trampolines are needed (e.g. Darwin ARM64), the DWARF LPT (Line
Program Table - see DWARF section 6.1) generation fails because the
replacement symbols are marked as external symbols and skipped during
the DWARF LPT generation phase.
Fixes #54406
