[PATCH] selftests: fix the broken individual test for x86

From: Bamvor Jian Zhang
Date: Tue Mar 21 2017 - 10:38:01 EST


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
