This commit removes blackfin support.
I'm open to re-adding blackfin after crosstool-1.23.0 is released, but
it is currently too difficult to port forward to newer versions of gcc
and uclibc.

This change, as per #222, reduces the number of supported releases of
gcc to the latest branch releases.
I noticed while doing this work that gcc-4.5.4 was never added, so I
moved patches for gcc-4.5.3 to 4.5.4 and updated the
bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed
upstream in the 4.5.4 release, so this patch is omitted.
I also bumped the avr sample to 4.9.3 from 4.9.2.
With the addition of gcc-5.x, the gcc release team now releases the
major.minor.0 versions, while updates to the branch are available in
svn/git. We'll address that when we get to issue #219. This change just
removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes
CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later.
This is the first of two part changes, as mentioned in #222.
This change is slated for release in 1.22.0. The next change will be
slated for 1.23.0, and will limit gcc versions to what is on
https://gcc.gnu.org under "Release Series and Status", which is
currently 4.9.3 and 5.2.0, although I will also support the previous
supported version. In this example that would be 4.8.5.
Last, but not least, this change also retires AVR32 support.

Some older versions of configure (including the one in GMP 4.3.2)
interpret the $ECHO environment variable as the `echo' utility to
use. CT-NG sets the variable to `:' and exports it if V=0 or V=1
is supplied, breaking the samples using such configure. This currently
includes bfin-unknown-linux-uclibc and powerpc-unknown-linux-uclibc.
Also, correct the description of the V= variable - V=0 is *not* the
default; in fact, default does not correspond to any of the V=[012]
values.

The gold linker cannot currently be built in a static toolchain build.
This may get fixed in a future version of crosstool-NG.
Also, there is a bit of weirdness here. versions of binutils >= 2.21
have GOLD (BINUTILS_HAS_GOLD), but that doesn't mean it should be used.
For instance, if the architecture is not supported.
So with that, we create a new hidden option: BINUTILS_GOLD_SUPPORT
Which in turn depends on BINUTILS_GOLD_SUPPORTS_ARCH, BINUTILS_HAS_GOLD,
and not STATIC_TOOLCHAIN... then replace anything that previously
depended on BINUTILS_HAS_GOLD with our new BINUTILS_GOLD_SUPPORT option.
This closes#210

- New configurations:
- CC_GCC_TARGET_FINAL:
Use the default targets "all" and "install" for the final compiler for
bare metal.
- Adding parameter "build_step" to function do_gcc_core_backend:
do_gcc_core_backend is used for the core compiler and in case of bare metal
for the final compiler, too. To have better control over the parameters for
the final compiler "build_step" is used.
- Used for proper logging.
- Use CT_CC_GCC_CORE_EXTRA_CONFIG_ARRAY or CT_CC_GCC_EXTRA_CONFIG_ARRAY.
- If CT_CC_GCC_TARGET_FINAL is set and the final compiler is build then the
make targets for the final compiler are used ("all", "install").

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 commit also closes#66

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.

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

Older branches of crosstool-ng continue to have eglibc support.
If you find issues with older branches, I'm always open to pull

Removing eglibc also frees up glibc cleanup and build optimization.
