Yes, ok, but I do not see any nice x86_64-related, let alone AMD
235e-related CFLAGS during the compilation.
So if the ECFLAGS doesn't work too well, isn't that a bug?
Because: why not optimize for target XYZ when gcc is already allowed to
use -O3?

W.r.t. progress: an initial database import worked. tv_grab_nl_py works.
Next weekend I can transplant the DVB-T PCI-card and make the move to
the new box.
It'll still run 0.21-fixes. 0.22-fixes the next step.
