e53becc70f examples/Makefile: give priority to pkg-config flags
In case CFLAGS/LDLIBS are already defined and conflicting with the
pkg-config flags, give priority to the latter since they are used to
detect compilation flags.

This should fix for example the case where there are many different
instances of a library, CFLAGS=-I/foo/include and pkg-config cflags say
-I/bar/include.
