+configure: fix calls to {gdlib,net-snmp}-config
+
+nut directly calls to {gdlib,net-snmp}-config. In Buildroot,
+those are not in the PATH, and nut would catch those of the
+system (if they are installed), or miss them entirely.
+
+Fix that by using environment variables that will tell where
+to look for them.
+
+Note: libusb also uses libusb-config, but only as a fallback
+if pkg-config fails. Since we ensure that pkg-config exists,
+and libusb is properly installed before we build nut, there
+is no need to fix the libusb-config calls, since they won't
+be called at all.
