[Buildroot] [PATCH 1/1] fs/common.mk: enable multithreaded xz compression

[james.hilliard1 at gmail.com]

From: James Hilliard <james.hilliard1 at gmail.com>

xz help indicates only 1 thread is used unless we set threads:
-T, --threads=NUM   use at most NUM threads; the default is 1; set to 0
                    to use as many threads as there are processor cores
