[Buildroot] [PATCH v2] toolchain: speed up sysroot lib copying

[Mike Frysinger]

The copy_toolchain_lib_root helper searches the entire sysroot, but is
only interested in files in certain subdirs.  So rather than waste time
in walking the entire tree, walk the few subdirs at the depth level we
are actually going to be poaching files from.
