Okay, what do you think about the attached patch?

For some documentation, see:

http://www.gnu.org/software/automake/manual/html_node/Usage-of-Conditionals.html

...or, for a real-world example, the upvoted answer to:

http://stackoverflow.com/questions/15368848/checking-environment-variable-in-make-through-automake

...or the contrib/minizip source in zlib:

https://github.com/madler/zlib/blob/master/contrib/minizip/configure.ac
https://github.com/madler/zlib/blob/master/contrib/minizip/Makefile.am

Of course, it's up to you whether to do it this way or in the somewhat
more traditional --with/--enable-something style.

G'luck,
Peter
