OK, solution :)
PB came from the arch designated as the compilation reference.
I applied Ian's patch (see [mythtv] [PATCH] mythtv/settings.pro lists 
wrong proc type for amd64) to declare the k8 architecture.
I also had to change sym link of gcc/g++/(gccdebug) to the 3.4 versions, 
and eventually the compilation went smooth. =)
Side note : I ran the 'make distclean' command to clear a pb with 
libqt.prl with my first attempt.

Now I'm quite pleased to report that compilation does fine on Debian 
AMD64 pure64 (alioth).
