I think requiring the host compilation is wrong in the first
place. Instead, when cross-compiling, Python should require that the
host python already exists - whether from a previous configure;make;
make install, or because a host Python had been there all along (it
doesn't even have to be the same Python version).

Likewise, building the host pgen in a cross-compilation should not be
necessary, since the pgen output is shipped with the source release.

configure already supports cross-compilation, so setting CC should not
be necessary (since it will automatically find arm-linux-gcc if you
have a GNU cross-compilation environment).

I don't volunteer to write patches, either, but I do volunteer to
review patches.
