Enable O and KBUILD_OUTPUT for kselftest. User could compile kselftest
to another directory by passing O or KBUILD_OUTPUT. And O is high
priority than KBUILD_OUTPUT.

Sorry for noticing this late, but this patch
(a8ba798bc8ec663cf02e80b0dd770324de9bafd9) is really annoying for
people who *don't* use these fancy options:

$ make -C tools/testing/selftests/x86 ldt_gdt_32
make: Entering directory '/home/luto/apps/linux/tools/testing/selftests/x86'
Makefile:44: warning: overriding recipe for target 'clean'
../lib.mk:55: warning: ignoring old recipe for target 'clean'
make: *** No rule to make target 'ldt_gdt_32'.  Stop.
make: Leaving directory '/home/luto/apps/linux/tools/testing/selftests/x86'

Is there any way that you can make this work again?
