powerpc selftests allow to override ARCH for cross-compilation by making
the first ARCH assignment weak.
Use the same approach in breakpoints, ipc and prctl tests to:
 - keep uname usage consistent across selftests
 - make it easier to cross-compile

test_bitmap, test_printf and prime_numbers are expected to be built as modules.

How does it make it easier to cross-compile? Could you please
elaborate on what this patch is fixing?

Also I would like to see 3 separate patches one for each
of the tests?

thanks,

Nevermind, ARCH was already a weak assignment. My patches changed the behavior.
I've been confused by the different approach used by powerpc vs
breakpoints/ipc/prctl tests.

Will you accept a patch to get rid on uname_M variable, keep ARCH
usage consistent across selftests?
In other words, align with the way it's done in powerpc test.
It won't fix any cross-compilation issues but improve consistency in the code.
