Makefile: Make pkg-config mandatory to find libpci

Browse Source 
Use `make HAS_LIBPCI=yes/no` to override the pkg-config detection and
`CONFIG_LIBPCI_CFLAGS` and `CONFIG_LIBPCI_LDFLAGS` to set cflags and
ldflags manually. The optional dependency of libpci libz, is
automatically handled by pkg-config.
