Add support for applying arch-specific patches found in
"patches/${pkgname}/${version}/${CT_ARCH}".
This is needed for applying a popular binutils patch specific for the
AVR architecture but which isn't isolated for AVR in binutils' code.
In this case, applying it for every architecture would end up bloating
binutils' "size" options with AVR specifics.
This feels like a bit of a hack but it is easy enough to support with
current crosstool-ng infrastructure, seems like worth it for this case.

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 adds support for the Atmel AVR 8-bit RISC architecture.
This is the first 8-bit architecture to be added to crosstool-ng so the
configuration options for 8-bit architectures are added here as well.
gcc has had support for AVR for quite a while, at least since the 4.3
series for the currently popular ATmega microcontroler series.
The AVR architecture only supports bare-metal toolchains.
gcc for the AVR 8-bit architecture, usually referred to as avr-gcc, is
commonly used in conjunction with the avr-libc library which provides
additional resources for the Atmel AVR 8-bit microcontrollers.
avr-gcc can also be found as a supported package in some recent Linux
distributions.

This option is old. GCC 4.3.x old. It isn't supported anymore, and just
confuses me. I'm not planning to support 4.3.x, or really anything older
then 4.7. So this option is gone to the wind.

This functionality was provided so that crosstool-ng could have a
further set of patches considered experimental and unsupported.
Now that musl-libc support is making it's way upstream in gcc, I'm
removing this support and the experimental musl patches.
In later commits, backports from gcc upstream will be added to the
supported patch sets to support musl-libc.

The gconv modules are present in the (e)glibc toolchains, and some
applications directly link with one or more of those modules (even
though the classic way of using them is by dlopen()ing them).
So, also look in /usr/lib/gconv when searching for libraries.

Glibc actually does create a build executable. It's under sunrpc and it's
called cross-rpcgen. It uses gettext, so if that's not available in a standard
place on your system (for example if you're using Mac OS X and Homebrew), then
you are all out of luck.

Without this canadion cross builds create invalid symlinks:
When the code in do_cc_core_backend is called there is no
${CT_TARGET}-gcc in the install directory. Therefore ext is empty and
we create a link to ${CT_TARGET}-gcc. The final compiler
step then installs ${CT_TARGET}-gcc.exe and creates a working
${CT_TARGET}-cc.exe symlink but we still keep the invalid link
as well.

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.
