espeakup Shouldn't Presume Pulseaudio

[Janina Sajka]

I believe Bill's  found the source of the problem at least for Fedora
users:

https://bugzilla.redhat.com/show_bug.cgi?id=799137

As I read this bug Fedora hard-locked pulseaudio in order to keep the
Fedora Live image within limits for a CD ROM. Unfortunately, we weren't
tracking this bug so didn't speak up on behalf of Speakup users. Of
course, there's no gurantee it would have mattered.

However, my reading of the comments in this bug suggests that it is
possible to compile Espeak to support all the "backend" options. So, I
guess we need to have a Speakup Modified compile of Espeak.

PS: My reading of the comments tends also to confirm my assertion that this
builtin "backend" support is indeed a design flaw in Espeak. Though, as
Willem has pointed out, not necessarily easily fixed.
