[Skiboot] [PATCH] external: Fix cross compilation issue

For some reason Makefile thinks compiler variables like CC is already
assigned and ignores CROSS_COMPILE variable. Hence I'm not able to generate
arm binary on x86.

This patch checks for CROSS_COMPILE variable and does forceful setting of
CC and LD variables.

Fixes: 3137d249 (pflash: Allow building under yocto.)
