libc/glibc: get rid of the now obsolete CVS stuff

It's now been a while that glibc switched to git from cvs.
Get rid of cvs to download glibc; this will make for a good
cleanup before we add git support! :-)

libc/glibc: add 2.11 and 2.11.1

Merge.

kernel/linux: remove legacy check

Now, we only support building with Linux >=2.6.27.
Get rid of the code that depended on <2.6.18.

binutils/elf2flt: activate elf2flt build

The code has been lying around inactivated for some time.
Let's enable it at last, and see if any one needs it.

arch: add basic m68k support

[yann.morin.1998@anciens.enib.fr: use defaults for CT_TARGET_ARCH]

global: do not offer the renice option, let's the user handle that

It's broken anyway. Eg.:
- user is already niced at 10
- user configures to renice at 5
- breaks because user is not allowed to 'boost' his/her nice value

Bette let the user handle the renice with:
nice -XX ct-ng 'action'

cc/gcc: add latest 4.4.3, propagate patchset from 4.4.2

Merge.

libc/uClibc: fix the breakage for x86 and Super-H, after the 32/64 merge
