We can just bruteforce the list. Ie decide that for every possible
version from 5.8.0 to 5.12.X, we add them to @INC.
5.8.0, 5.8.1, 5.8.2, etc
then 5.10.0, 5.10.1, etc, to 5.10.5 
and then 5.12.0 to 5.12.X 

And keep the binary only for the current version.

For now, we have this : 
  -Dinc_version_list="5.12.5.12.2/%{full_arch} 2 5.12.1
5.12.1/%{full_arch} 5.12.0 5.12.0/%{full_arch} 5.10.1 5.10.0 5.8.8 5.8.7
5.8.6 5.8.5 5.8.4 5.8.3 5.8.2 5.8.1 5.8.0 5.6.1 5.6.0 

That seems something that we could generate with some loops, if we do
not care of adding non existent perl version in the mix. 

The only issue I can see is for performance, but since we are still
doing a lookup for perl 5.6.0 who was released 11 years ago, I do not
think a few more bogus directory will matter so much. ( and I think all
our rpm were migrated to 5.10 at least ).
