Subject: [PATCH] x86, build: Set -fno-pic for 32/64-bit kernels
Date: Fri, 19 Aug 2016 16:23:17 -0700	[thread overview]
Message-ID: <1471648997-26976-1-git-send-email-carlos.santa@intel.com> (raw)

Make the -fno-pic compiler flag common for both 32 and 64 bit kernels.
The GCC toolchain in Android still enables -fpic by default
causing the build to break.
