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

 [ Building gcc-2.95.3 on cygwin yields a compiler that sticks a .exe

   on the end of every executable, even if they're linux executable.

   This is highly annoying, and causes glibc build failures that look like this:

     mv: `.../bin/makedb.new' and `.../bin/makedb' are the same file

     make[2]: *** [.../bin/makedb] Error 1

     make[2]: Leaving directory `.../gcc-2.95.3-glibc-2.1.3/glibc-2.1.3/db2'

   The mainline solves this with http://gcc.gnu.org/ml/gcc-cvs/2001-04/msg00440.html,

   but that doesn't apply cleanly to gcc-2.95.3.

   So, I'm using

   http://www.uclinux.org/pub/uClinux/uclinux-elf-tools/tools-20030314/gcc-2.95.3-cygwin-020611.patch

   This is the only patch in crosstool that *isn't* suitable for the mainline.

   I can live with this patch simply because crosstool does not build

   compilers that target cygwin or VAX/VMS. 

   If that ever changes, I might need to try applying the real patch.
