I've also noticed a problem with gcc being rebuilt. It seems to be from
do_headerfix() and:

diff --git a/meta/recipes-devtools/gcc/gcc-configure-common.inc b/meta/recipes-devtools/gcc/gcc-configure-common.inc
index d014980..3a82720 100644

 addtask headerfix after do_unpack before do_patch

+
 do_configure_prepend () {
        # teach gcc to find correct target includedir when checking libc ssp support
        mkdir -p ${B}/gcc

"fixes" it. I merged the other fix but this one needs a little bit more thought. bitbake-diffsigs can also mislead:
