[CONSOLIDATED PULL 26/41] utils.bbclass: add helper function to add all multilib variants of a specific package

[Saul Wold <sgw@linux.intel.com>]

From: Richard Purdie <richard.purdie@linuxfoundation.org>

This is useful for the scenario where we want to add 'gcc' to
the root file system for all multilib variants
