Why?
The Linux kernel is a freestanding environment.
Omitting -ffreestanding only for allowing gcc to automatically use
builtins isn't a good idea (as we have already seen).
We can easily enable as many gcc builtins as we want.
We could even do this for all platforms in include/linux/string.h
It might make sense to do this properly since it could e.g. be the gcc
builtins produce no worse code than the inlines in
include/asm-i386/string.h.
But if this should be done, let's do it right and explicitely.

Gentoo kernels are 42 times more popular than SUSE kernels among
KLive users (a service by SUSE contractor Andrea Arcangeli that
gathers data about kernels from many users worldwide).
There are three kinds of lies: Lies, Damn Lies, and Statistics.
