Interesting. Can you confirm that Richard's commit:

    kernel: Fix non linux-yocto builds

    After the recent kernel changes, non linux-yocto builds stopped working
    properly for two reasons:

    a) ${S} was being reset to ${WORKDIR}/git for example and STAGING_KERNEL_DIR
       did not contain the source

    b) Most builds were using ${B} == ${S}

    This patch adds a fixup to the unpack function to handle the case where
    ${S} != ${STAGING_KERNEL_DIR} and also set up the infrastrcture so that
    B != S for kernel builds from now on. The kernel build system is one of the
    best for supporting this and there is no good reason not to take advantage
    of it.

------------

Is in your tree ? it should be fixing things up and allowing the source to
be found.

Alternatively, if you drop the explicit set of S, does the build start working
again ?
