Summary: Modules are linked with more libs than necessary

Initial Comment:
The link command for modules receives a generic LIBS variable that contains more libraries that needed for some of the modules. As a result they are linked against libraries from which they do not use any symbol, resulting in unwanted dependencies. Any distribution  that packages some modules separately may have undesired dependencies for those modules as a result.

I think that the LIBS varaible for modules should only contain the bare minimum (which is most likely only libc) and let the modules add the extra libs they need on a per module basis.

In the attached file you can see the extra unused libraries that a debian build has found for some of the modules packages separately.

Message:
Some fixes caused problems in several cases, because every distribution and
some other OS (like solaris) have different dependencies and library
configurations. So i'll close this one for now.

Now also fixed for bdb_recover, the modules mi_xmlrpc, perlvdb and
snmpstats remains.

I don't want to change them at the current state of development, as i
don't have time to test them sufficiently. I think its ok to fix them in
1.5, decrease priority.

Hi Dan,

there are actually two problems: 

Some problems include to many libs in their makefile, i've fixed this for
db_unixodbc.
This is not so easy to fix for perl and perlvdb, because they use perl
tool to generate the dependencies.

The other one is, as you wrote, that the LIBS variable from the root
Makefile contains to many libs. This is mainly an issue if you've enabled
TLS, as you can see in your error log.
