Subject: uClibc: Don't use CROSS, use CROSS_COMPILE instead

As per:
http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/Makefile.help?id=044843f002f666db3bc06c513ed6291a00ad1225

CROSS= is for compatibility, but we plan on dropping older uClibc
versions, and adding uClibc-ng and uClibc-snapshot support.

Use CROSS_COMPILE instead.
