Can we try to get this sorted out properly instead of constantly 
fiddling with it?

Currently we use -ffreestanding on some architectures and fix breakages 
on the other architectures when they arise.

The options I see for getting this fixed properly are:
- use -ffreestanding on all architectures or
- don't use -ffreestanding on any architecture and move the string
  functions (and perhaps other functions if required) out-of-line

I'd prefer the first option, but I know that not everyone agrees with me.

No matter which option we choose, if we get an agreement on this one
I can send patches for it.
