Crosstool-NG 1.22.0 Released

[Bryan Hundven <bryanhundven at gmail dot com>]

Hello all!

I'm excited to annouce that we have cut the 1.22.0 release of
crosstool-NG!

While this release series went on for much longer then I wanted
(considering the last release was 2015-05-25), a lot went into this
release. So the term "Feature-release" seems a bit understated.

This release starts our process to minimize the number of versions we'll
support in future releases of all components. Components to see some of
this already are GCC and uClibc.

This release also brings the addition of uClibc-ng and updates to the
experimental support for MinGW-w64. We're hoping to stabilize MinGW-w64
in the next release.

Preparation for multiple compilers has been added, but the only compiler
supported at this time is GCC. In the future we will be adding support
for LLVM/Clang.

For new architectures, we now support Xtensa (with cpu overlays) and AVR
support for 8-bit architecture.

Now that musl-libc changes are in GCC-6 development branch, we have
updated our patches by backporting them to as far back as 4.8.5.

One of the biggest process changes is that we now test every
pull-request with a set of samples on:
https://travis-ci.org/crosstool-ng/crosstool-ng
In the future, I will be working to purchase dedicated hardware for
hosting jenkins-ci, and not just running build tests, but also being
able to run gcc test-suite.

Many thanks to the people who contributed to this release:

      Added new config ISL_V_0_14_or_later and ISL_V_0_12_or_later to select     proper configure options for isl 0.14.x and 0.12.x in 121-isl.sh.
      Fix for issue #142:     Configure for for core GCC did not use Core gcc extra config.     Use now config variable CT_CC_GCC_CORE_EXTRA_CONFIG_ARRAY.
      Fix for issue #147:     Enable definition of "Use __cxa_atexit" for bare-metal systems, if the used     libc does provide such a function. The libc configuration have to select     LIBC_PROVIDES_CXA_ATEXIT.
      Adding patches for binutils version 2.25.1 as copy of 2.25.     Support binutils 2.25.1 in configuration.     Note: The patches do apply, but I didn't check the resulting tools.
      Support mpc 1.0.3 in configuration.
      Support mpfr 3.1.3 in configuration.
      CC_GCC_CUSTOM is no longer part of the gcc version choice, but an independend     configuration to enable CC_GCC_CUSTOM_LOCATION.
      LIBC_NEWLIB_CUSTOM is no longer part of the newlib version choice, but an     independend configuration to enable LIBC_NEWLIB_CUSTOM.     All newlib versions >=2.0.0 does provide __cxa_atexit. To enable this function     in GCC, all versions >=2.0.0 does now select LIBC_PROVIDES_CXA_ATEXIT.
      BINUTILS_CUSTOM is no longer part of the binutils version choice, but an     independend configuration to enable BINUTILS_CUSTOM.
      Adding CLooG 0.18.4.     Adding isl 0.15.     Added following constrains:        isl 0.14 and 0.15 require  CLooG 0.18.4 or later.        isl 0.11.1 and 0.12.2 require CLoog older than 0.18.4.
      Fixed issue 173 and 174.     gcc 5.x   -> isl 0.12.2, 0.14 0.15     gcc < 5.x -> cloog < 0.18.4  -> isl 0.12.2, 0.11.1               -> cloog >= 0.18.4 -> isl 0.14
      Added additional newlib specific target flags with new option     LIBC_NEWLIB_TARGET_CFLAGS.
      Adding missing if/else blocks in do_gcc_core_backend for CT_CC_GCC_LIBSSP,     CT_CC_GCC_HAS_LIBQUADMATH and CT_CC_GCC_LIBQUADMATH (--en/disable-libssp,     --en/disable-libquadmath, --en/disable-libquadmath-support) from function     do_gcc_backend.
      Removed doubled setting of --disable-libmudflap in do_gcc_core_backend.
      Added additional environment variables for gcc build (make) with new option     GCC_EXTRA_ENV_ARRAY.
      Remove isl 0.15, because it will not compile with gcc 5.2.0 without patching gcc.
      Set language to 'bash' to get rid of interfering environment variable CC=gcc.
      Synchronize CT_CC_GCC_USE_LTO parameter setting in do_gcc_backend with the one     from do_gcc_core_backend, by adding "--enable-lto"/"--disable-lto".
      Remove CC_GDB_CUSTOM from the version choice.
      Using "all" and "install" targets in do_gcc_core_backend if configured.     - 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").
