Hi,

This won't help completely unless you also clean up all archs to use the 
same mappings to the builtin functions.

The main problem I had with -ffreestanding is that it's awkward to map a 
library function to the builtin function and also provide the fallback 
from lib/string.c.
If you look at asm-m68k/string.h I once tried this with the mem* functions 
and I still have the duplicated memcmp in arch/m68k/lib/string.c.
(You could argue that it would be easier to just remove the define for 
memcmp in this specific case, but I'm interested in the general case.)

bye, Roman
