[Buildroot] [PATCH] package: coreutils: allow building individual binaries

[Markus Mayer <mmayer@broadcom.com>]

We add configuration option BR2_PACKAGE_COREUTILS_INDIVIDUAL_BINARIES
so that coreutils can be built and installed as individual binaries.

The approach is modelled after Busybox's similarly named configuration
option.
