package/gnuradio: add optional support for orc
When orc was compiled before, gnuradio will use it as optional
dependency:
$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/gnuradio-config-info | grep NEEDED
[...]
0x0000000000000001 (NEEDED) Shared library: [liborc-0.4.so.0]
[...]
Apparently there is no option provided by the build system to
en-/disable support for orc:
