Patch applied with updated strcpy.c.

Did you ever manage to look at the problem from before Christmas re: thumb-2 and crt0.S init_hooks? I was hoping you might come up with a solution that would work for all involved.

Is there are way to (optionally) force newlib to use the generic versions instead of the "optimized versions" below "machine"?

From my experience, in longer terms, such optimized (asm) versions tend to break/rot. In such occasions, falling back to the generic versions is quite handy.
