Description:
If one compiles mysql with the --with-zlib-dir=${ROOT4BUILD}/usr
rule, configure tries to find libz.a. However, this does not make
much sense, when mysql is dynamically linked against libz and
even fails to run configure, when the static library is not available
(for whatever reason ...)

So acinclude.m4 should check for libz.a || libz.so ...

This is the same issue as with openssl lib in 4.0.16 (see bug report 1923).

How to repeat:
mkdir -p /tmp/zlib/{include,lib}
cp -a /usr/lib/libz.so* /tmp/zlib/lib/
cp /usr/include/{zconf,zlib}.h /tmp/zlib/include/

./configure --with-zlib-dir=/tmp/zlib

Suggested fix:
Use the standard checks for libraries

Pushed into the 4.1 sources, will be included in 4.1.16.
To be merged into 5.0 as soon as possible, hopefully in time for 5.0.16.

Patch will allow any "libz" shared libraries to be used, 
regardless of their filename extension (".so", ".sl", ".dylib").
