    Subject: [PATCH 1/1] kbuild: Fix clang detection
    We cannot detect clang before including the arch Makefile, because that
    can set the default cross compiler. We also cannot detect clang after
    including the arch Makefile, because powerpc wants to know about clang.
    Solve this by using an deferred variable. This costs us a few shell
    invocations, but this is only a constant number.

    in the Linux kernel.
    This will allow us to make better decisions about when to run tests
    later on for gcc features.
