Subject: top: Rename back CROSS_COMPILE_PREFIX to CROSS_COMPILE
X-Git-Tag: v0.1~100
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fd7199920ed9cee84b07234db85b8fb3943664c2;p=platform%2Fkernel%2Fopensbi.git

top: Rename back CROSS_COMPILE_PREFIX to CROSS_COMPILE

The name CROSS_COMPILE is an industry standard used across
open-source project to specify cross-compiler prefix.

In fact, distro build systems such as buildroot and yocto
assume CROSS_COMPILE to be supported by projects added
as packages to these build systems.

This patch rename back CROSS_COMPILE_PREFIX to CROSS_COMPILE.
