    tools: gpio: Use !building_out_of_srctree to determine srctree · 4a6a6f5c

    make TARGETS=gpio kselftest fails with:
    Makefile:23: tools/build/Makefile.include: No such file or directory
    When the gpio tool make is invoked from tools Makefile, srctree is
    cleared and the current logic check for srctree equals to empty
    string to determine srctree location from CURDIR.
    When the build in invoked from selftests/gpio Makefile, the srctree
    is set to "." and the same logic used for srctree equals to empty is
    needed to determine srctree.
    Check building_out_of_srctree undefined as the condition for both
    cases to fix "make TARGETS=gpio kselftest" build failure.
