shared library for espeak

[Doug Sutherland]

Well check the Makefile for espeak. With lots of software
these days, especially if it uses the autoconf, the Makefile
will check if you have various libraries and use them if it 
finds them. I don't know if espeak requires JACK, but if 
not, there should be a way to exclude it by modifying the 
Makefile generated by autoconf. If it doesn't use autoconf
then check the static Makefile and look for the reference 
to JACK.
