You are right! The description of CROSS_COMPILE was not very good.

This variable holds the host-infos of the runtime-platform.  The
CROSS_COMPILE is set (as example for a powerpc based crosscompiler) to
"powerpc-linux-".

A cross-compiler and a for-cross-compiler binutils-package, whose
binaries starts with "powerpc-linux-" as prefix, exist in the
(crosscompile-)system.

   /cc/powerpc/usr/bin/powerpc-linux-strip
   /cc/powerpc/usr/bin/powerpc-linux-ld
   /cc/powerpc/usr/bin/powerpc-linux-gcc
   /cc/powerpc/usr/bin/powerpc-linux-g++
   ....
   .
   .

The Makefiles of the Kernelsources are good examples.
   cd <KERNELSOURCES>
   grep -R CROSS_COMPILE *


But I think, my patch is not good! We need a more configurable way, like
a STRIP="/usr/bin/strip" in the makepkg.conf.


For now, its all clear?

Have a nice Day,
eS.eF.
