arch/arm: no need to check for the ABI option

The ABI option can not be set if EABI was selected,
so no need to check for it.

arch/arm: add support for noMMU

Some ARM cores do not have an MMU (eg. Cortex-Mx and Cortex-Rx series).
Thus, allow the user to configure out the MMU for ARM.

libc/newlib: allow using CVS snapshots

The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.

functions: allow using sub-dir of a module

Some projects' module (eg. newlib) are checked-out into a sudirectory
rather than into their own directory. Handle this case in the CT_GetCVS
function.

libc/newlib: allow using newlib with archs other than avr32

libc/newlib: fix namespace in config file

C library config options should be prefixed with 'LIBC_'.

libc/newlib: cleanup the build and finish steps

build step:
- ./configure
- remove glibc-specific options
- pass the target CFLAGS in the correct variable
- make:
- build in //

finish step:
- print proper message in finish step

libc/newlib: fix host/target confusion

newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run

debug/dmalloc: fix handling of threading model

config: add help for the MMU/noMMU entry

config/libc: move around hidden config options

This yields a cleaner .config file that is easier to read.

config/arch/arm: default to EABI

docs: adding naming conventions for crosstool-NG

docs: fix chapter spacing

version: update to 1.5.0+hg

Merge.

scripts: replace calls to svn with calls to hg in script to renumber patches

docs: get rid of any reference to the now long-gone svn repository

docs: move the "contributing" section to overview.txt

docs: configure no longer accepts --with-contrib

It's been a while that configure does not recognise --with-contrib.
Applying contibutions is to be done manually, using patch.

configure: force using the C locale to check messages

configure: fix --with-foo=/path/to/foo

When a required tool is specified with --with-foo, store the variable
in the list.

samples: fix the avr32-unknown-none sample

Bizarely enough, binutils-2.18 fails to build when CONFIG_SHELL is set
to /bin/bash (although it has code to recognise bash and act accordingly).

Waht is really strange is that it does build when CONFIG_SHELL is set
to /bin/sh, *although* /bin/sh is a symlink to /bin/bash. WTF?!?!
