It does - CC=gcc

The effect of DEB_CONFIGURE_SCRIPT_ENV is that the package tries to
cross build using gcc which simply breaks.

Unset DEB_CONFIGURE_SCRIPT_ENV for the crossbuild and gcc gets the
value from --host and works fine.

This is ONLY relevant for cross building and cross building support has
been entirely rewritten recently. The main change was to stop passing
CC to all packages so that certain packages could get a sensible
setting for CC_FOR_BUILD. The $(CC) setting should come from --host, NOT
from DEB_CONFIGURE_SCRIPT_ENV.

Unset DEB_CONFIGURE_SCRIPT_ENV and the cross build gets $(CC) from --host
as it should.
