Both invocations need to explicitly set CC - because of older configure
scripts in the first case.

Errgle. It _can_ affect the configure process. Say for instance, squid.
Squid uses test binaries to determine socket sizes, maximum fd limits
and the like, which it can't do during a cross compile run, so the cross
compiler (individual) has to provide those on the command line.
Cross-compiling certainly reduces the 'magic' detection that can take
