From f92d19e0ef9bbbb2984845682e740934ad45473b Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 9 Jul 2018 17:46:02 -0700 Subject: [PATCH] kbuild: Use HOST*FLAGS options from the command line Now that we have the rename in place, reuse the HOST*FLAGS options as something that can be set from the command line and included with the rest of the flags.
