external toolchain: slightly optimize the copy of the toolchain sysroot
The sysroot of an ARM CodeSourcery toolchain takes about 1.4 GB of
space, but 1.1+ GB of this space consists in locale-related
information which Buildroot doesn't use. By skipping the copy of those
unused files, we save quite a bit of time while importing the
toolchain sysroot.
