    gcc-cross: Avoid races with gcc_stash_builddir
    
    Its sad we need to do this but do_install and do_populate_sysroot appear
    to change the files in ${B} and this breaks if something works in parallel
    like gcc_stash_builddir. We've seen a few too many race errors on the
    autobuilder which appear to be from this so make things run in sequence
    deterministically for now.
    
    An example failure was this from do_populate_sysroot whilst stash_builddir was running
    in parallel:
