Subject: [PATCH v4 6/9] selftests: Set CC using CROSS_COMPILE once in lib.mk
Date: Wed, 11 Mar 2015 15:06:02 +1100	[thread overview]
Message-ID: <1426046765-19289-6-git-send-email-mpe@ellerman.id.au> (raw)
In-Reply-To: <1426046765-19289-1-git-send-email-mpe@ellerman.id.au>

This avoids repeating the logic in every Makefile. We mimic the
top-level Makefile and use $(CROSS_COMPILE)gcc.
