96245813d8 kconfig: remove useless 'default n' 
kconfig bools are disabled by default, so specifying 'default n' is useless and
noisy. This patch removes all occurrences of 'default n'.

ccbfef2376 libc: hide no-thread for those C libraries that do not support it 
Building non-threaded glibc has been unsupported for a long time, now:
  http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html

As eglibc is a spin-off of glibc: ditto.

So do not offer that possibility in the menuconfig.
Thanks to Thomas Petazzoni for spotting, and helping to solve, the issue!

c49c8b1ac2 scripts/xldd: install only when shared libs enabled 
When the toolchain has no support for shared libraries, there is no
point in installing the cross-ldd helper.

b81d232a9b kernel: add mingw 
Add the option to build a cross-compiler for kernel type 'mingw'.
The resulting cross-compiler can be used to build applications on a Linux host
that can be run on a Windows target.

Compiler is build using the mingwrt and w32-api packages aviable from the
MinGW project (http://sourceforge.net/projects/mingw).

The windows headers (w32-api package) are extracting with the kernel_headers
step The libraries and other headers from both packages are build and
installed in the various steps of libc

43ca5b4095 config: add support for a second part of the generated choices 
Some components have configuration options that can depend on
generic options, so they should go below those.

uClibc for example:
- has its own options (wchar...)
- uses the generic options (threads...)
- if linuxthreads chosen, offers two impls

So we need to be able to split the components options in 2,
one part that is above the generic options, and one part that
ends up below the generic options.

30481d01ce Move the threading model choice back to the C library menu: 
- the threading models available are dependent on the C library used
 - it is thus easier to first select the C libary, and then the threading model, rather going back to the toolchain menu.

You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(
