It's a pretty rare issue these days. You have to provide an absolute pathname, which is always frowned upon. Further, if you cross-build in a chroot, it's a non-issue.

You also can't run the resulting executables so
post-build testsuites can't be run.

Issue number 2.

Yep- but only relevant for a small set of packages.

OK. That might be true for gcc, but how about gcj? Or other compilers?
I'm also thinking about python that emits byte-code. Is this code
machine independent? I'm not sure; Could google or read, but just want
to mention....

Gcj?!  Er, no problem there...

I'm sure there could be some Python issues (We have not had to tackle that one). When we start implementing a cross compile feature, we would naturally would take on the easy and critical packages first. Python could come later.

Yes, cross compilation is an interesting; At least for me and I would be
happy to be a bit involved; You never stop learning...
