As long as non-java package will work with any version of java, then
I don't.

It isn't. I investigated locations on different architectures with
different JDK versions and I found there is no one place where header
files and libraries reside. Even your example hardcodes archicture name
into the path. See former `pl' spec file for the mess of conditions
which has been needed before.

My approach allows to get proper paths for current JDK. It's absolutly
independent on platform, JDK version, and distribution tweaks (like
Fedora alternatives). I believe my tool works everywhere (even out side
Fedora or with manually installed JDK).
