It is not necessary indeed. I did not mean it was.

Recent enough :)

The -mno-thumb-interwork flag is needed to cover precisely the armv4t case,
and is compatible with armv5t. I think you can run into troubles when
using your patch on armv4t, but not on armv5t, hence using the flag without
the patch is a better solution.
