Merge the uClinux/noMMU stuff back to /trunk:
- merge Linux and uClinux back to a single kernel
- add ARCH_USE_MMU and acquainted config options that
architectures can auto-select
- make binutils and elf2flt two "Binary utilities" that
go in a single common sub-{menu,directory} structure

 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.0/gentoo/00_all_gcc-trampolinewarn.patch

 	This trivial patch causes gcc to emit a warning whenever

 	it generates a trampoline.  These are otherwise hard to

 	locate.  It is rigged to default ON - to have it default

 	to OFF remove the text 'Init(1)' from the common.opt

 	patch, leaving just 'Common Var(warn_trampolines)'.
