Subject: Re: [PATCH v2 16/16] selftests: vDSO: vdso_standalone_test_x86: Switch to nolibc

This addition of "| headers" breaks O=build builds. ie this:

$ make O=build-x86 allnoconfig -s -j 14
$ make O=build-x86 -s -j 14
$ make O=build-x86 kselftest-all -s -j 16 &> /dev/null || true
$ make O=build-x86 -s -j 14

Fails with:

***
*** The source tree is not clean, please run 'make mrproper'
*** in /home/jgg/oss/wip/kselftests_dirty
***

Because the build now spews stuff outside the build directory that it
should not do.. Bisection points to this patch and removing the "|
headers" makes it stop doing that..

Any idea how to fix it?

Thanks,
Jason
