Darwin, CTF, BTF: Do not run the DWARF debug link for BTF/CTF [PR101283].
Darwin uses an efficient two-stage process for debug linking.
The static linker (ld64) notes the inputs required but does not
link the debug. When required / on demand the debug is linked
into a separate package by the debug linker (dsymutil). At
present none of the Darwin tools consume or understand BTF/CTF.
The static linker silently accepts the sections (but will not
act on them as containing anything to be processed).
However, the debug linker produces a warning that it has been
presented with input with no [DWARF] debug content:
warning: no debug symbols in executable (-arch x86_64).
This causes several testsuite fails with excess errors.
