It means that the SRCREV for the branch doesn't have the
following commit covered:

commit 2b412826bbeb4a16abe2ea74f2456ab880c6e3c1
Author: Bruce Ashfield <bruce.ashfield at windriver.com>

     perf: hard-code NO_LIBPERL/NO_LIBPYTHON

     ExtUtils::Embed ccopts is getting the host's -I/usr/local/include and
     using it to compile perf, which results in a compilation error that
     started appearing just recently.

     This turns the code that makes use of ExtUtils::Embed off and simply
     hard-codes NO_LIBPERL.

     It does the same for LIBPYTHON while we're at it, since it probably
     suffers from a similar underlying problem and just by chance hasn't
     broken anything yet.

     This will be re-enabled after I familiarize myself with the perf
     recipe and am able to create a proper fix.

The kernel repo has this, and I thought that the meta-intel
emenlow had an updated SRCREV .. but your build error indicates
otherwise.
