Aha. Maybe we should just add it to the whole libRivet build, in which
case the flag will be passed automatically to the rivet-buildplugin script.

James, do you know if there is an alternative on Macs? I believe that
the -as-needed flag (implicitly switched on?) allows the linker to be
selective about what symbols it imports from a linked library, which
presumably was overzealous at doing so when encountering the
fastjettools plugin...
