Makefile.modules.3rd specifically allows you to overwrite APXS, when
needed

i can see that now, in the sense that i assumed a user's point of view

instead of patching apxs, maybe using it's -S switch (overwriting a
given variable) would help here?
like would the following patch to Makefile.modules.3rd (<warning>i gotta
run in a few for the weekend, so while this is an
offhand/untested/unfinished/broken prototype, you should get the
idea</warning>) adress your (at least some of) concerns?
