Both for Z80 and for the more general question: Is the rest of the toolchain
capable of dealing with that without any adjustments? Are other tools on the
target (non-GNU linkers etc) capable of (correctly) consuming such objects?

Furthermore, looking at just symbol_relc_make_sym(), I can't help the
impression that the symbol names produced there could conflict with (quoted)
ordinary symbols. Such potential conflicts would be a reason to be careful
with enabling of this functionality.

In any event such enabling would imo not only want but need to come with at
least one testcase.
