    rs6000: __builtin_mma_disassemble_acc() doesn't store elements correctly in
LE mode

    PR96236 shows a problem where we don't correctly store our 512-bit
accumulators
    correctly in little-endian mode.  The patch below detects when we're doing
a
    little-endian memory access and stores to the correct memory locations.
