I was noticing that $extra_user_env was inconsistently used in
100-gcc.sh. I don't feel comfortable having just any make flag or
environment variable passed to make from a config file. If a specific
option needs to be passed to make for gcc, then a specific kconfig
option should be added for that make flag/option/env.

The two gcc backend functions are getting very close to being duplicated
code. To help in the process of merging the two backends, this change
syncronizes the two functions so they are easier to diff.
This commit has no functional changes.

If destdir was / and prefix began with /
then we would attempt to install libelf
to a path beginning with // which is a
UNC path on Cygwin. This is generally
incorrect.

On Windows a build failure can be triggered during the
build of the static iconv if a dynamic iconv is already
present:
There's a circular dependency between libiconv and gettext
which (on a system with a dynamic gettext (and thus iconv)
installed in the system prefix) causes a failure to build
iconv.exe statically if it is built with nls ..
.. Which needs gettext
.. which depends on libiconv
.. so libtool finds a dynamically linked libgettext.la
.. and therefore presents ld with the dll import library
libiconv.dll.a when linking iconv.exe
.. as well as the static libiconv.a that it has just built!
.. leading to multiply defined symbols from iconv.
Therefore, we build it without nls. If it later turns out
that we need it to be built with nls, then I will have to
build it in two passes (common practice when bootstrapping
GNU/Linux distros, MSYS2 and probably Cygwin and Homebrew).

Cygwin follows POSIX IEEE Std 1003.1, 2004 Edition spec
for the select() fuction as described at:
http://pubs.opengroup.org/onlinepubs/009695399/functions/pselect.html
.. so we must #include <sys/select.h> for the declaration.

Define PICFLAG, UNDEFINEDPREAMBLE and UNDEFINEDCODE to nothing since Windows
doesn't have -fPIC (GCC warns) and can't handle undefined variable references

Build shared builds for host unless CT_STATIC_TOOLCHAIN.
In all other situations, build statically, as before.
It is necessary that the static/shared-ness of expat matches
that of gettext on Cygwin/MinGW-w64 as they can't be linked
together if they don't match, so we follow the same logic.

This commit updates the build scripts to match the new usage of
CT_GetCustom from the previous change.
Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
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.

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

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

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.

If building a static toolchain, the ldflags option passed to
do_binutils_backend is overridden when we set `LDFLAGS=-all-static`.
We should pass `LDFLAGS=${ldflags} -all-static` in this case.

Now that versions of gcc that required PPL are no longer supported
( >= gcc-4.5.x AND <= gcc-4.7.x )
...we no longer require PPL or CLooG/PPL.
This commit:
* Removes PPL
* Removes CLooG/PPL
* Updates the documentation
* Updates build script for CLooG and GCC
* Removes PPL and CLooG/PPL from scripts/addToolVersion.sh and
scripts/showSamples.sh
* Adds ISL to scripts/addToolVersion.sh and scripts/showSamples.sh

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.
