mips: allow to disable prefetch support in memcpy/memset
There exist some problem with the new memcpy/memset functions
imported from GNU libc/newlib. If you have any problem
with the new MIPS optimized assembly try to disable
prefetching support.
Thanks to Rene Nielsen and Matthew Fortune analyzing the
problem so far.
