Description:
Reduces langdefs.py warnings in doc build

Doesn't quite get rid of them - one to sort.  This has been interesting
to fix.  There were 2 issues - building the regtests before building the
docs meant that the translations weren't available, and this threw about
20 warnings.  I've swapped their order in the makefile with no apparent
other problem.  Building the manuals threw about 10 warnings.  However,
it doesn't appear possible to build the translations before the manuals
because of a dependency.  To that end, I've added an environment
variable to the call to lilypond-book, and suppressed the warning when
this variable is set.
