Subject: [PATCH 18/36] perf s390: Always build with -fPIC

From: Hendrik Brueckner <brueckner@...ux.vnet.ibm.com>

On s390, object files must be compiled with position-indepedent code in
order to be incrementally linked or linked to shared libraries.
Therefore, add -fPIC to the CFLAGS for s390 to ensure each object file
is built properly.
