[RFC v3 0/3] Fix errors when try to build kvm selftests on specified output

[Xiaoyao Li]

Hi Shuah,

Hope you're happy with this version that I only touch KVM's Makefile.

I attempted to build KVM selftests on a specified dir, unfortunately
neither	"make O=/path/to/mydir TARGETS=kvm" in tools/testing/selftests, nor
"make OUTPUT=/path/to/mydir" in tools/testing/selftests/kvm work.

This series aims to fix them.

Patch 1 and Patch 3 are the fix patch, please see the seperate for details.
While Patch 2 is more or less an fix for the future issue, since it works
without Patch 2 currently.

Changes in v3:
 - Drop all the patches that touch things out of KVM
 - Create OUTPUT dir in KVM's Makefile
 - Correct the INSTALL_HDR_PATH in KVM's Makefile

Changes in v2:
https://lore.kernel.org/kvm/20200325140133.103236-1-xiaoyao.li@xxxxxxxxx/
 - fix the no directory issue in lib.mk
 - make kvm fixes seperate patch
 - Add the patch to fix linux src tree not clean issue

v1:
https://lore.kernel.org/kvm/20200315093425.33600-1-xiaoyao.li@xxxxxxxxx/

Xiaoyao Li (3):
  kvm: selftests: Fix no directory error when OUTPUT specified
  kvm: selftests: Use the right INSTALL_HDR_PATH when OUTPUT specified
    and MAKELEVEL is 0
  kvm: selftests: Fix header path when built from parent level with O
    specified
