proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+Gnulib intentionally does not have a gets module, and now that C11

+Subject: [PATCH] make perl & examples optional
+
+The normal bison program does not require perl to build or run, so lets
+soften that requirement in the configure script.  We now warn if its not
+found, and we make the examples logic depend on that.
+
+* configure.ac: Change AC_MSG_ERROR to AC_MSG_WARN for perl.
+Add an --enable-examples flag.
+* Makefile.am: Only include examples/local.mk when ENABLE_EXAMPLES.
