Can you share your mk.conf?

I suspect the issue is that you're setting ABI=64 unconditionally in
your mk.conf, and that is bleeding into the cross-build settings.

With the patches I'm sitting on (to be committed soon after 2023Q3 is
branched, or at least posted here for preliminary review if they're
not quite ready yet), it'll be easier to separate parameters like that
in native/cross packages.  But for now, if you have any ABI setting in
mk.conf, you'll need to make it conditional on ${USE_CROSS_COMPILE:tl}
== "yes"/"no".
