Subject: [PATCH] Make m68k cross compile like every other architecture.

From: Rob Landley <rob@...dley.net>

Rip out hardwired cross compiler name assumption that only m68k makes.

When you cross compile, you have to set the prefix CROSS_COMPILE to your
cross compiler prefix.  You need to do this for all targets (arm, mips, ppc,
x86-64 on x86, etc).  This is not specific to m68k, and this value is
supplied _to_ the build, not supplied _by_ the build.

The build shouldn't unconditionally overwrite the existing value of this
variable with one it makes up.  It has no idea what I called my cross compiler.
