[PATCH V2 27/30] perf build: adding X86 auxiliary specific flags
From: Mathieu Poirier
Date: Sun Oct 18 2015 - 14:26:45 EST
Adding an X86 specific flag to split AUX components that are
generic and specific to architectures. That way the auxiliary
area mechanic can be compiled in for other architecture without
including X86 specific code.
