The configure script locates the orcc program via pkg-config, which specifies it in ROOT which is a cross-compiled version that probably is not executable. It should be in BDEPEND to install a native version, and the program path needs to be overridden for configure. (It links against liborc, too, so it also needs to remain in DEPEND.) This looks like it is fixed in future versions with meson.
