So in that case there is:

addtask make_scripts after do_patch before do_compile
do_make_scripts[lockfiles] = "${TMPDIR}/kernel-scripts.lock"
do_make_scripts[deptask] = "do_populate_sysroot"

which forces the make_scripts task to run before compile. I don't see
how that could therefore fail? :/

Do you have a copy of the exact log? I'm wondering if this is another
variant of the bitbake dependency bug I just tracked down
(http://git.yoctoproject.org/cgit.cgi/poky-contrib/patch/?id=7b49d336c4672f3dfa78e1c3f1f5c7384264a118)
