Hi David,

Please find below an ARM optimised memchr; it needs
Thumb2 and at least ARMv6T2. In the case of thumb or being on
an earlier architecture it just includes the generic .c version.
On a new enough architecture the routine is always assembled
as Thumb2.

Thanks very much for supplying this patch. I see no problems with it, so I have checked it in to the sources.

Cheers
  Nick
