From ff0a1a3da605ca157e3f3d0ed2d8b9acb30c2f69 Mon Sep 17 00:00:00 2001
From: Alexey Neyman <stilor@att.net>
Date: Tue, 4 Jul 2017 19:19:42 -0700
Subject: Switch gen-kconfig to new framework

Also:
- Move companion_* to comp_* to match the kconfig symbols
- Replace bootstrap with former gen-versions.sh
- Fold *.in.2 into their respective first parts; this moves common
  options to the end - if it is undesirable, inclusion of *.in
  can be moved where *.in.2 used to be (but that will also move
  version selection after common options).
- Retire addToolVersion.sh (may later replace with a more
  comprehensive script that tries to download the added tarballs,
  copy the patches and try to apply them, and create a version.desc).

-
-          Valid options for all tools:
-            --stable, -s, +x   (default)
-              mark the version as being stable (as opposed to experimental, below)

-

-            add stable current version 2.6.19.2 to linux kernel:
-              ${myname} --linux 2.6.19.2
-
-            add experimental obsolete version 2.3.5 and stable current versions 2.6.1
-            and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
