How about having an exclusion option?  So that know incompatible
versions could be %defined once and we wouldn't need a series of
if/%if statements?  With wildcarding you may be able to do away with
for-each-2 and for-each-3?

%define incompatible "2.7 3.*"
rpm-pyconfig --foreach --exe --exclude "%incompatible"\
    "cp -a ../pristine @confsrcdir"

for the ppc case above, perhaps further conditionals could be added:

%define incompatible "2.7:$1"
rpm-pyconfig --foreach --exe --exclude "%incompatible" --arg %{ppcarch} \
    "cp -a ../pristine @confsrcdir"

the last example would need to be much better thought out.
