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
thing when we bump versions.
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
used as a production toolchain.

As posted on http://www.eglibc.org/
====================
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.

No longer recommended practice to use --enable-add-ons=nptl, so
for 2.20 and later (along with custom glibc), don't add the

This change removes 1.0.3 and 1.1.3 and linker regession patches for

We add 1.0.4, and a patch needed for gcc-4.9.x which defines

This patch adds initial support for musl-libc.
Musl-libc versions currently supported:
* 1.0.3 (Stable)
* 1.1.3 (Previous Mainline)
* 1.1.4 (Mainline)
Futher improvements are needed.
* gcc-4.9.x has issues (Might be fixed in musl-1.1.4).
* Multilib support is needed.
* Checks to make sure paths are correct.
* Move to 2-step gcc build. 3-step build is not necessary.

There is no need to differentiate the win32 threads case, since we
can cosider them to be the native implementation on Windows.
Besides, with the previous patch, nothing uses it anymore.
So, just remove it.

Use a more coherent naming for the options. This will help commonalise
the native case (e.g. NPTL on Linux, win32 on Windows), and add alternate
implementations (e.g. musl.)

LinuxThreads are dead. Buried 6 feet under. Long forgotten.
