As I've tested, need to autoreconf to pick up new autotools rules 
applied with patches.
So if call only ./configure after appliyng patches it wouldn't work as 
configure file is not re-created by autotools.

Maybe I have to suggest to netsnmp upstream as Issue to update 
"configure" file?

Thank you!
