It is not gcc which is generating those error messages.  It is the
linker.  I can't imagine an ARM linker which does not support those
relocations, so something odd is happening, and I don't see how it
could be in gcc.  I don't see those error messages in GNU ld or gold,
so: what linker are you using?
