Looks like it. Best thing is to try. To be sure what configure came up 
with have a look at bin/c4che/default.cache.py.

Yes, but only for cross-built packages (for example not to xslt package 
which generates documentation). Last time I checked the candidates were:
- Python (but you NEED a good python2.7-config, the CPython one is no 
good for cross builds)
- ncurses
- if you are NOT using the bundled Heimdal, you need something for Kerberos.

> Alternatively, is there some way to get "find_program" to use the current PATH (which in my case should have identified the cross variants of these scripts)? If this latter consideration worked then it would suffice to require that the cross variants of all 'pkg-config'-like scripts simply be in the PATH (ahead of the host variants).
That's exactly what it does - scan all directoried in PATH according to 
the order in PATH. I verified it by putting a breakpoint at find_program().
