832bee87c0 Make build-all rely on kconfig options.
For that, make CT_BUILD_TOP_DIR a non-settable config option (so that it is
recursively expanded with CT_HOST/CT_TARGET). Use a common prefix, with
same default as for regular sample build.

Use showConfig.sh to determine host toolchain path (for canadian crosses)
and build directory to be removed.

Remove LIBC_SYSROOT_ARG (unused).

3e4d4870c9 Simplify config saving.
Instead of hardcoding defaults in saveSample.sh.in, have the same
defaults in config. Then we can just remove them when saving the
config.

c0cc73cd6f Install canadian crosses into a separate subdir.
Makes them sorted out by host, and removes the need for similar hack in
samples.mk.

Change how canadian crosses are named: using `=' character resulted in
Glibc build failure.

Move loading config into a common function, CT_LoadConfig.

9d835eddcf config: Remove CUSTOM_LOCATION_ROOT_DIR
On top of making <component>_CUSTOM much more complicated to rewrite,
you couldn't depend on a requirement for all of the components to treat
custom sources the same with it around.

If you need a custom source for a component, define it in the component.

2a89c32193 gcc: Remove gcc <= 4.7.x
As per #222, in crosstool-NG >= 1.23.0, we will only support:

 [upstream supported gcc versions] - 1

As of this writing, these versions are:

* 5.2.0
* 4.9.3
* 4.8.5 (the -1, since development on 4.8.x is now closed)

I plan to keep 4.8.5 around because of some architectures having issues
with over-optimization or just faulty optimization in the 4.9.x and
possibly newer versions.

I also cleaned up a requirement for glibc to depend on >= gcc-4.6.x for
>= glibc-2.20, but since the lowest gcc we support after this change is
>= 4.8.5, this condition can go away.

Patches for older gcc versions are removed in the next commit.

This closes #222

67e6896c2b Remove support for experimental patches and musl patches
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.

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.

74d555b2c3 scripts: add support for building manuals
Add support for building the HTML and PDF manuals for the major
components.  Implement for binutils, GCC, GDB, and GLIBC.

Always build all manuals and install a subset.  Be explicit about the
subset to reduce the clutter and to avoid getting copies of common
manuals like bfd from all of the sourceware based components.  Downside of
being explicit is that you need to update it when a new component
comes along.

Build the manuals as part of the last GCC build, namely 'cc' for glibc
based ones and cc_core_pass_2 for baremetal.

Currently, the mirror can be used either:
 - as a fallback in case upstream is unavailable (default behavior)
 - as the preferred source for downloads

But the most common use-case seems to provide a truely-LAN mirror

source for the tarballs.

So, make the following changes;
 - if a mirror is specified, always try that before trying upstream

7817bcebe7 config: add an option not to remove the destination directory
In certain circumstances, removing the destination/installation directory
is a bad idea. For example, when the build environment is already taking
care of sanitising the build tree, and pre-installs stuff in there, it is
a very bad idea to remove the destination directory.

This happens now in buildroot, as the crostool-NG backend now installs the
toolchain in the common host-tools directory, and pre-install there a few
host-utilities (eg. host-automake and host-gawk).

Provide a config knob to turn on/off the removal of the destination
directory, defaulting to 'y' (previous behavior), and forced to 'n' when
used as a backend.
