Andy Lutomirski report that build individual testcase in x86 is broken:

$ 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'

This patch fix this issue by adding default OUTPUT and convert
target in Makefile of x86.

And also mention this use case in Documentation/kselftests.txt

I don't think this is a good fix, it only fixes this one Makefile, and
it's quite verbose. But if it really bothers Andy then it would be OK as
a stop-gap for 4.11.
