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.

Similarly to what we've just done to prevent both --with-arch and
--with-cpu, we do the same to prevent using both --with-cpu and
--with-tune at the same time, since --with-cpu should fully imply
the CPU to tune for (and gcc now errors out when both are specified.

Normally, a specific CPU fully implies the architecture level. For
example, a cortec-a8 is forcibly an armv7, so spwecifying both is
redundant, and even dangerous (as incompatible values may be passed).
So far, gcc was pretty happy when both were specified at the same time,
and some time ago, it started being a warning, and only recently was it
turned into a hard error.
So, hide the architecture level prompt when a CPU has been specified.

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

In later commits, backports from gcc upstream will be added to the
supported patch sets to support musl-libc.

This change needs another change from pull request #81, but it's kind of
a chicken/egg scenario. The 'select's in CC_GCC_5_1 need to be
refactored a bit, and would be easier to test if gcc-5.1.0 was commited.
Most of the refactoring will happen with CC_GCC_HAS_GRAPHITE.

====================
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.

We had following problem: We're building a toolchain with an old glibc
version for compatibility with old Linux distributions (glibc 2.9). This
version requires make < 4 to build. However, the configure script of
glibc looks for make in the order "gnumake", "gmake" and "make". So when
"gmake" is available in the system (which is the case on Gentoo Linux
per default, unfortunately), then configure finds the system gmake 4.1
instead of the ct-ng make 3.82.
This patch adds an option to install a symlink so that 'gmake' is also
available in the old version when building toolchains.

but when building a canadian baremetal, the repair_cc

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.
