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

     1 Original patch from H.J. Lu, as reported there:
     2 http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html
     3 
     4 fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.
     5 The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
