package/Makefile.in: Do not use CPPFLAGS for hardening options

Browse Source 
The hardening options are compiler flags, not pure pre-processor flags, so
put them in CFLAGS, not CPPFLAGS.

This fixes build errors where -D_FORTIFY_SOURCE=2 whas put in CPPFLAGS and
then applied to configure tests which could fail since the required -O2 is
only in CFLAGS.
