classpath: inherit pkgconfig

It fixes this error:

| checking for pkg-config... no
| *** The pkg-config script could not be found. Make sure it is
| *** in your path, or set the PKG_CONFIG environment variable
| *** to the full path to pkg-config.
| *** Or see http://www.freedesktop.org/software/pkgconfig to get pkg-config.
| configure: error: Library requirements (gtk+-2.0 >= 2.8 gthread-2.0 >= 2.2 gdk-pixbuf-2.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
| NOTE: The following config.log files may provide further information.
| NOTE: .../work/core2-64-oe-linux/classpath/0.99-r3/build/config.log
