Understand. I am sorry I do not know this use case before. And I read
kselftest.txt again, I do not find this use case is mentioned. So,
I add a few lines in kselftest.txt to avoid break this use case in future.
Is there any other use cases I should test?

Here is a fix. I could build individual test case in x86 and build the whole
x86 test cases successful respectively. And I do a quick test for all the
subsets. Please review the patch if it is make sense to you and Michael.
At the same time, I am buildind and testing all the testcases.
Michael: could you please do me a favor to test the powerpc part? Thanks.

Subject: [PATCH] selftests: fix the broken individual test for x86
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 removing the slash after OUTPUT.
And also mention this use case in Documentation/kselftests.txt
