This commit adds support for the avr-libc C library.
According to the project page at http://www.nongnu.org/avr-libc , the
avr-libc package provides a subset of the standard C library for Atmel
AVR 8-bit RISC microcontrollers. In addition, the library provides the
basic startup code needed by most applications.
Support for this library in crosstool-ng is only enabled for the AVR
8-bit target.
The avr-libc manual and most distributions build the AVR 8-bit gcc
toolchain with the "avr" (non-canonical) target.
Some experimentation also led to the conclusion that other (canonical)
targets are not very well supported, so we force the "avr" target for
crosstool-ng as well.
The manual also recommends building avr-libc after the final gcc build.
To accomplish this with crosstool-ng, a new do_libc_post_cc step is
added, in which currently only avr-libc performs its build, and is a
no-op for the other libc options.

This commit updates the version knobs so that oldconfig does the right

Also, we update stable to 1.0.5 and experimental to 1.1.9.

While we do want users to be able to use the mingw from git, being under
the experimental umbrella makes it more obvious that this should not be

====================
EGLIBC is no longer developed and such goals are now being addressed
directly in GLIBC.
====================
I'm not interested in maintaining build support for unsupported
software.
Older branches of crosstool-ng continue to have eglibc support.
If you find issues with older branches, I'm always open to pull
requests.
Removing eglibc also frees up glibc cleanup and build optimization.

Can safely skip the core pass-1 for normal baremetal builds,
but when building a canadian baremetal, the repair_cc
functionality (GCC_FOR_TARGET) in gcc.sh will force the
core pass-2 to attempt to build gcc and libgcc without a
${CT_TARGET}-gcc existing, causing a failure on
${CT_TARGET}-gcc -dumpspecs > tmp-specs

As per the glibc release notes for 2.20:
--------------------------------------------------------------------------------
All supported architectures now use the main glibc sysdeps directory
instead of some being in a separate "ports" directory (which was
distributed separately before glibc 2.17).
--------------------------------------------------------------------------------
There isn't a ports directory anymore. So disable using and forcing it.

svn is needed to download eglibc from the upstream repository.
In some situations, though, it can happen that:
- the developpers' machines do not have svn
- a LAN mirror has been set-up with pre-downloaded eglibc tarballs

So, if svn is missing, just say so, and add a comment in the

By default, recent versions of glibc and eglibc will build some
functions that take format strings (eg. printf, syslog...) with
run-time checks against some format string attacks. This is
called a fortified build.
Unfortunately, this fails somehow while building the instrumented
version of syslog, with some kind of circular dependency...

behind EXPERIMENTAL for daring users...
