On the other OS platforms, in case a zlib is found on the system :

we use it from the system .
Wouldn't it be more consistent to have zlib=bundled as well as default for
the other UNIX platforms + MacOSX ?
( people who wish to use the system zlib still can configure it )
Otherwise we often run into using old zlib installations at build time which
might not be desired.
It was a deliberate change in JDK 9 to use the system zlib if possible.
Windows is the outlier. If you through the archives of core-libs-dev
then you should find several discussions about this, I think the most
recent was in 2016, subject line "JDK-8031767 Support system or
alternative implementations of zlib".
