After Kbuild introduction, the CROSS_COMPILE environment variable has been set to some default value (prefix arm-linux-).
Note that this is quite a long-standing thing. Perhaps we're now not detecting a native build when we used to?
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
