FS#12051 - Building rbspeex is broken on Cygwin

DetailsTested at r29689, gcc 3.4.4. When trying to create a voice file in Cygwin, the following comes out (taken from STDERR):

"make rbspeexenc" works fine on my Cygwin. Just compiled it using r29692.

I found a solution. I removed all speex-related packages and after that rbspeexenc built without errors. Perhaps this should be noted in the Cygwin development wiki page.

There's another catch: gcc4 doesn't support -mno-cygwin anymore. Depending on your installation gcc is gcc4, not gcc3. I'm considering to (a) remove -mno-cygwin when building rbspeexenc since the binary isn't usually distributed separately (if it's distributed building with MinGW works fine) and (b) change the Makefile to not use an installed libspeex and instead use the Rockbox implementation to avoid issues with the installed version (current Cygwin has a MinGW cross compiler but no libspeex package for it)
