[Skiboot] [PATCH] Makefile: Support CROSS_COMPILE as well as CROSS

[Michael Ellerman]

A lot of projects use CROSS_COMPILE for specifying the cross compile
prefix, so support that as well as CROSS.

For example this allows a user to set CROSS_COMPILE once in their
environment and build both Linux & Skiboot with the same setting.
