[PATCH v3 2/9] build: pull common fragments into a common.rules file

Johannes Berg johannes at sipsolutions.net
Mon Aug 31 05:28:53 EDT 2020 

From: Johannes Berg <johannes.berg at intel.com>

Some things are used by most of the binaries, pull them
into a common rule fragment that we can use properly.
