It was at all times in the exp version in my exp tree,  for 2 reasons :
1) the code used to find correct archdefs has to be debugged too in new 
versions.
2) in new ("unstable" like 3.9...) versions, archdefs are not even available 
for quite some time.
That version was copied (not by me ...) to the distribution.

You're quite right that it is high time to send those bug-reports upstream, if 
none of us is
willing to look himself into the cause ...
(Workarounds for your above-mentioned problem would be easy : either "-Si 
archdef 0",
or forcing the use of PPCG[45]32AltiVec.tgz _ say with a -A flag 
(but there is already special code (due to Dominique Dhumieres) in the 
confflags for G4's,
so the whole thing would need rethinking..).
But please file bug-reports upstream, so we get real corrections !
