Subject: [PATCH 08/14] KVM: selftests: Probe -no-pie with actual CFLAGS used
 to compile

Probe -no-pie with the actual set of CFLAGS used to compile the tests,
clang whines about -no-pie being unused if the tests are compiled with
-static.

  clang: warning: argument unused during compilation: '-no-pie'
  [-Wunused-command-line-argument]
