So (assumink JDK means Development Kit) the directory is not a part of
JDK and should be moved somewhere outside. Consider what's the purpose of
splitting icedtea8-jdk from icedtea8-jdk-base then.

Symlink and the libjvm.so of course, but this is in icedtea8-jre-base subpackage which
WAS pulled by gdal itself.

Yes, something like icedtea8-jre (with R: icedtea8-jre-base itself) should
be used to system-select the JRE to be used.

Moreover, we should have sth like oracle-jre package with appropriate
symlink and fake provides for the systems with self-installed Oracle
non-distributables.
