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.
