New port jakarta-commons-lang3.

This is a repo-copy of jakarta-commons-lang, updated to revision 3.4.
It can co-exist with jakarta-commons-lang. The newest version upstream
is actually 3.6, but support for using apache-ant to build was dropped
between 3.4 and 3.5. Apache OpenOffice 4.2.0 will require 3.3+.

Add NO_ARCH.

Modernize by using option helpers.

Get rid of the JDK_API!= stuff, which looks like it no longer did
anything useful.
