BTW, the issue seems to be that the call is going through the PLT but the relaxation offset check assumes that it's jumping directly to the symbol so it incorrectly concludes that it's within bounds to relax to a compressed jump. (It seems like we could avoid going through the PLT anyway. If so, it would be good to optimize that, as that's a preexisting behavior).
