[proaudio] ardour 3.9999 convert to waf??

[allan <sonofzev@xxxxxxxxxxxx>]

Hi Folks

I know this is probably a big job but is it possible for ardour 3.9999
to be converted to use waf to compile instead of scons.. It appears that
waf is the preferential way and scons is becoming deprecated. 

I have been unable to compile from the ebuild for the last few versions
but have successfully built it using the waf method. 

Regards

Allan
