History of the xscale machine dir?

I guess that you can blame me.  It was a long time ago, but I think that 
what actually happened was that someone at Intel asked us (Red Hat) to 
provide some hand written assembler versions of the string and memory 
functions in order to speed up the xscale targeted version of the 
arm-elf toolchain.  I wrote them and later contributed them to the 
newlib project, but it was very remiss of me not to include copyright 
notices on the files.

I believe however that it is safe to assume that since I was working for 
Red Hat at the time, the sources are covered by Red Hat's blanket FSF 
copyright assignment.

Please do this.
