That's not what the commit message said. The commit message said:

    nettle: disable assembly optimizations for ARMv7M
    It's thumb2-only and it requires ARM instructions.

So it did not say at all that nettle requires Thumb-2 *and* classic. It
said that ARMv7M provides only thumb2, and that nettle requires ARM
