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.

The idea is that you *should* be able to take a perf.data file from one
architecture and process it on another architecture.
