1b31314488 CT_GetCustom: Rewrite function to meet expectations
The previous version of CT_GetCustom was a bit... funky.
It didn't handle custom versions to location very well.

This new version is exactly as it appears:

CT_GetCustom <name> <version> <location>

The name is the beginning of the archive (file or directory).
The version is the second half of the archive.
The location is where it can be found. This should be made an absolute
path, but this version is expecting the path in kconfig to be absolute.

A file should extract to a directory: <name>-<version>
A directory will be copied to: <name>-<version>

This keeps our expectations of what we should get.

0041a8b105 CT_Extract: Move check extracted up
If we are using a custom location, and that custom location is a
directory that does not have an associated tarball, then we shouldn't
warn about not finding a tarball in CT_TARBALLS_DIR if
CT_SRC_DIR/.<basename>.extracted is found.

If the extracted file is not found, then we can warn that the tarball
was not found then error out that the tarball is missing.

6f8e89cb5c consistency: Use exported variables of required tools
We check for apps:

* make
* sed
* grep
* awk
* libtool/libtoolize
* install
* patch
* and more

...during configure. Our scripts should be consistent about using the
variables that define where the found tool was found.

Of course, we do hard-link these tools in buildtools, but that should be
a backup for the components we are building. Our scripts should always
use the tools we find.

c4d14a97ad functions: Add global functions for manipulating kconfig options
This commit adds 4 new functions to aid in the process of managing a
kconfig .config file:

* CT_KconfigSetOption <option> <value> <file>
* CT_KconfigEnableOption <option> <file>
* CT_KconfigDisableOption <option> <file>
* CT_KconfigDeleteOption <option> <file>

(akin to how buildroot manages the uClibc.config)

These functions are global so that we can manage any component that also
uses kconfig, or to be able to use it internally on Crosstool-NG's
kconfig files.

Last but not least, be consistent and update sed to be ${sed}!

219c5e932f functions: add support for arch-specific patch
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.

b8e64a0c08 avr-libc: add support for avr-libc C library
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.

cd47c091ba eglibc: Remove eglibc support
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.

85622fdd49 Add main EXPERIMENTAL_PATCHES setting
This change adds support for experimental patches to be introduced to
crosstool-ng. The patches enabled by this option are to be located here:

    patches/experimental/<package>/<version>/XXXX-NAME.patch

Where, XXXX is the patch number to be applied in order, like:
    0001-some_patch_one.patch
    0002-some_patch_two.patch
    9999-some_patch_to_be_applied_last.patch

In the first patch series, all patches in the EXPERIMENTAL_PATCHES
option will be applied all at once, or none at all.

In a later [RFC] patch, I plan on adding finer tuned patch
enable/disable options based on the name of the patch and where it is
located in the patches/experimental sub-tree. So the name of the patch
should use underscores between words in the patch name.

e284b218a7 arch/avr32: Fix download of header files
This patch fixes the download of the avr32 headers in crosstool-ng by
fetching them directly from Atmel's web site instead of the now-broken URL
given by the original author of the avr32-header-fetching modification,
who fetched them from a copy on his own, now-defunct server.

It also adds the necessary logic to extract from a zip file, as that is
how the headers are packaged.

To configure it for avr32 after launching ct-ng menuconfig in an empty
directory:

       Paths and misc options ->
               Shell to use as CONFIG_SHELL = sh
       Target options ->
               Target Architecture = avr32
       Toolchain options ->
               Tuple's alias = avr32
       Binary utilities ->
               binutils version = 2.18a
       C compiler
               gcc version = 4.2.2
       C-library
               newlib version = 1.17.0
               Enable IOs on long long = yes
               Enable IOs on floats and doubles = yes
               Disable the syscalls supplied with newlib = yes

CONFIG_SHELL is necessary to get round the "fragment: command not
found" bug when binutils-2.18 is configured using bash.

Prepared against crosstool-ng mercurial trunk on 31 March 2012.

150f500426 arch: allow adding a suffix to the arch-part of a tuple
For some architectures, it is legit to have an alternate value in the
'architecture' part of the tuple. For example:
    armv5te-*
    armv7a8-*

Besides, some packages expect the tuple to reflect the arch variant
(eg. openMPI) to detect the variant's capabilities (eg. atomic
primitives).

This patch adds an option for the user to specify a suffix to be added
to the arch-part of the tuple.

c0475188cb functions: add new helpers that create a dir and cd/pushd into it
A lot of places are currently doing:
    mkdir -p foo/bar
    cd foo/bar

Or even:
    mkdir -p foo/bar
    pushd foo/bar
    [...]
    popd

Provide both wrapper to ease doing this.

Fix that.

964f379a42 scripts: fix dumping execution backtrace
Dumping the backtrace has been broken since changeset #652e56d6d35a:
    scripts: execute each steps in a subshell

We can spawn sub-sub-shells in some cases.

The way the fault handler works is to dump the backtrace, but to avoid
printing it once for every sub-shell (which could get quite confusing),
it simply exits when it detects that it is being run in a sub-shell,
leaving to the top-level shell the work to dump the backtrace.

Because each step is executed in its own sub-shell, the variable arrays
that contain the step name, the source file and line number, are lost
when exiting the per-step sub-shell.

Hence, the backtrace is currently limited to printing only the top-level
main procedure of the shell.

Fix this thus:
- when dumping the bckatraces for the steps & the functions, remember
  it was dumped, and only dump it if it was not already dumped
- at the top-level shell, print the hints

Also, rename the top-level step label.

4fc56b1d14 arch: add softfp support
Some architectures support a mixed hard/soft floating point, where
the compiler emits hardware floating point instructions, but passes
the operands in core (aka integer) registers.

For example, ARM supports this mode (to come in the next changeset).

Add support for softfp cross compilers to the GCC and GLIBC
configuration. Needed for Ubuntu and other distros that are softfp.
