My point is that we are relying on assigning default prefix (i.e.
arm-linux-)

For example OSELAS toolchains can have an arbitrary prefix
(e.g. arm-linux-gnueabi-).

When I cross compile I set explicitly "CROSS_COMPILE=<toolchain> make"
and it works as it should (with or without this patch). Such approach
seems natural for me.

However, I don't know what is the exact rationale for seting this
arm-linux- prefix to CROSS_COMPILE.
I can only guess, that it is connected with situation when one just
type "make" on x86_64 host and expect u-boot to be CROSS_COMPILE'd
out of the box.

Unfortunately this doesn't work with ARM host emulated with qemu (like
OBS). Here when I type "make" I expect that "native" gcc for arm will
run without even touching CROSS_COMPILE environment variable.

Any idea how to fix this is more than welcome.

Best regards,
Lukasz Majewski
