Hi guys,
I just found that the gcc-runtime-nativesdk has different task signature for
task do_patch, comparing to that of gcc-cross-initial. This would cause a
do_patch failure if we use OEBasicHash as the BB_SIGNATURE_HANDLER. By
comparing their sigdata files, it turns out that the difference comes from the
dependency to the variable PN in do_patch(See the following output of
diffsigs). It is not designed, because all gcc family recipes share the same
source therefore should have the same signature for all do_patch tasks.

I'm wondering if it is a correct way to fix this issue by excluding the PN from
do_patch dependency:
diff --git a/meta/recipes-devtools/gcc/gcc-common.inc b/meta/recipes-devtools/gc
index e89a7c0..57668f9 100644
--- a/meta/recipes-devtools/gcc/gcc-common.inc

# We need to ensure that for the shared work directory, the do_patch singatures
# The real WORKDIR location isn't a dependency for the shared workdir.
src_patches[vardepsexclude] = "WORKDIR"
+should_apply[vardepsexclude] = "PN"
