Don't fail to build documentation if kindlegen doesn't exist

Check for kindlegen in configure and do nothing in the MOBI build
rule if the binary didn't exist.

This is still a bit of a hack since the rule will run with every
invocation of make.  The target needs to be made conditional.  But
at least this way make all in the documentation directory doesn't
fail.
