Please pardon my late reply was super busy with internal activities.

As for known problem of gmon that includes libc headers unfortunately
nothing has been done on that front. That's because we have a
workaround with disabling libgmon in Buildroot.

I'll ping our gcc guy but I don't think things will change soon here
again because it doesn't look as a blocker.

So probably rsync hook is a way to go for now.
