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
--- a/meta/recipes-devtools/gcc/gcc-configure-common.inc
+++ b/meta/recipes-devtools/gcc/gcc-configure-common.inc
@@ -77,6 +77,9 @@ do_headerfix () {
 
 addtask headerfix after do_unpack before do_patch
 
+CROSS_TARGET_SYS_DIR[vardepsexclude] = "PN"
+CROSS_TARGET_SYS_DIR[vardepvalue] = "1"
+
 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:

$ ls *headerfix*
gcc-cross-4.6.2+svnr181430-r20.do_headerfix.sigdata.84c0ca9d0fc07438f453910901a222b6
gcc-cross-initial-4.6.2+svnr181430-r20.do_headerfix.sigdata.84c0ca9d0fc07438f453910901a222b6
$ bitbake-diffsigs *headerfix*
Dependency on task gcc-cross_4.6.bb.do_unpack was added
Dependency on task gcc-cross-initial_4.6.bb.do_unpack was removed

Note that the hashes are the same and these are in fact identical. The
dependency hashes *do* match and its bitbake-diffsigs that is wrong here
as the file changed names.

Cheers,

Richard
