[PATCH v2] Makefile: kselftest and kselftest-clean fail for make O=dir case

[PATCH v2] Makefile: kselftest and kselftest-clean fail for make O=dir case

[Shuah Khan]

kselftest and kselftest-clean targets fail when object directory is
specified to relocate objects. Fix it so it can find the source tree
to build from.

make O=/tmp/kselftest_top kselftest

make[1]: Entering directory '/tmp/kselftest_top'
make[2]: Entering directory '/tmp/kselftest_top'
make[2]: *** tools/testing/selftests: No such file or directory.  Stop.
make[2]: Leaving directory '/tmp/kselftest_top'
./linux-kselftest/Makefile:1185: recipe for target
'kselftest' failed
make[1]: *** [kselftest] Error 2
make[1]: Leaving directory '/tmp/kselftest_top'
Makefile:145: recipe for target 'sub-make' failed
make: *** [sub-make] Error 2
