Bugzilla Bug 191278

This one had a few fixes and no open bug : 

from -r1 to r2 :
  Call only once the autotools with eautoreconf, do not install destop entry
  as executable (reported by Josh Saddler), fix automagic on portaudio,
  regenerate doc with doc useflag, make flac optional, parallel make appears
  to work thus drop -j1, add missing dep for docbook2html when regenerating
  doc

from current stable to r1 : 
  >=flac-1.1.3 compatibility

x86 stable

stable on ppc

media-sound/hydrogen-0.9.3-r2 on AMD64:

Emerges fine, No Collisions. Works fine with demo songs provided. Although my
terminal was spammed with "[ERROR]     AlsaAudioDriver
[alsaAudioDriver_processCaller] XRUN" while it was running.
