Comment (by munster):

 Replying to [comment:1 Sebastian Huber]:
 > The -mfpu=neon-fp16 is not supported by RTEMS as far as I know. If you
 want to add support for it, then please add a new multilib for this.
 I did that, please see the attached file.

 For example, `-mfpu=neon` and `-mfpu=neon-vfpv3` are the same. Also
 `-march=armv7-a` and `-mcpu=cortex-a9` are very similar if not the same.
