Subject: Fix build without Lout.

Reported by rvclayton@verizon.net (R. Clayton).

* doc/user/Makefile.am (BUILT_SOURCES): Leave empty when !HAVE_LOUT.
  (skrflags): Add `-e "(define %have-lout? ...)".

* doc/user/loute.skb (Additional Markup): Don't evaluate
  `src/lout-illustration.skb' when not %HAVE-LOUT?.
* doc/user/eq.skb (Equation Formatting): Use 'lout as the renderer only
  when %HAVE-LOUT?.
* doc/user/src/eq3.skb: Likewise.
