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/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

 you have to actually list out the multilibs you want or you will end up with

 just one when using targets like 'sh4-linux-gnu'.

 The resulting toolchain can't even build a kernel as the kernel needs to build

 with the nofpu flag to be sure that no fpu ops are generated.

 Here we restore the gcc-3.x behavior; the additional overhead of building all

 of these multilibs by default is negligible.
