  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

  PPL: Remove support for PPL and CLooG/PPL

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

I know that sounds like a lot for one commit, but it was all kind of
inter-tangled.

  gcc: CLooG should be optional for configure

Because >= gcc-5.x does not require cloog, it should not be forced on
the command line arguments for configure if graphite is enabled.

Make CLooG optionally added, if it is needed (aka: <= gcc-4.9).

  gcc: Gnu OpenMP support depends on threading

Instead of checking if thread support is enabled during the build, move
the check to kconfig-time. Since if threading support is not availble,
libgomp should not be available either.
