I'm not sure that putting the package CFLAGS into AM_CPPFLAGS won't
cause problems. While it's very likely that $(PKG_CFLAGS) only
contains preprocessor directives, we don't know that and have no way
of enforcing it. I think it would be better to take the safe route and
put them in AM_CFLAGS even if it means -I include paths will be passed
when linking.
