Not really.

Please always post the input command line that is given to libtool,
that gives valuable hints as to whether libtool generated the
--whole-archive arguments.

OK, this is kind of weird.  Libtool only uses whole-archive for
convenience archives, and those are normally not installed.
Libtool has a conceptual difference between static libraries and
convenience archives; the former are considered normal libraries,
just not shared, the latter are intended to be incorporated "as a
whole" into a final output, be that a library (normal) or a program.

It is recommended against installing such a convenience library,
and actually, one has to hack a bit in order to do so.

Do files /usr/lib/mysql/libmysqlclient.la and /usr/lib/mysql/libz.la
exist, and if yes, could you please post their contents?

Thanks,
Ralf
