[Khem Raj]

commit: http://git.uclibc.org/uClibc/commit/?id=b18b4210a84f87f7155683d73a0ab924c34fa3f2
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

In some case where CROSS is defined to be empty
we define CROSS_COMPILE ?= CROSS so at this point
it will be defined but will be empty so check
for the same
