Subject: [PATCH] Makefile.PL: fix cross-compilation with gdlib.pc

Cross-compilation will fail if gdlib.pc does not contain any cflags.
Indeed, if cflags is empty, Makefile.PL will use the default value for
INC (i.e. -I/usr/include -I/usr/include/gd)

It should be noted that gdlib-config has been dropped from gd since
version 2.3.0
