[build] Use -no-pie on newer versions of gcc

Some distributions patch gcc to generate position independent
executables by default.  We currently include a workaround to check
for this and to add -fno-PIE -nopie to CFLAGS if required.

Newer patched versions of gcc require -fno-PIE -no-pie instead.  Check
for both variants.
