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.
The build does not unconditionally overwrite the existing value of this
variable. You can specify the name of your cross compiler like this:
make CROSS_COMPILE=m68k-linux-
BTW, m68k-linux-gnu- is the default name for a m68k cross compiler.
For "make headers_install" this is not good.
But I see there is confliting usages here.
1) current functionality makes it easy to build a cross compiled m68k
2) suggested functionality makes it easy to do make headers_install
Btw. if you did:
CROSS_COMPILE ?= m68k-linux-
then I could do:
export CROSS_COMPILE=my-m68k-linux-
make
and still get the expected result.
