Aishwarya reports that KVM selftests for arm64 fail with the following
error:
| make[4]: Entering directory '/tmp/kci/linux/tools/testing/selftests/kvm'
| Makefile:270: warning: overriding recipe for target
| '/tmp/kci/linux/build/kselftest/kvm/get-reg-list'
| Makefile:265: warning: ignoring old recipe for target
| '/tmp/kci/linux/build/kselftest/kvm/get-reg-list'
| make -C ../../../../tools/arch/arm64/tools/
| make[5]: Entering directory '/tmp/kci/linux/tools/arch/arm64/tools'
| Makefile:10: ../tools/scripts/Makefile.include: No such file or directory
| make[5]: *** No rule to make target '../tools/scripts/Makefile.include'.
| Stop.
It would appear that this only affects builds from the top-level
Makefile (e.g. make kselftest-all), as $(srctree) is set to ".". Work
around the issue by shadowing the kselftest naming scheme for the source
tree variable.
