patch for the configure-script for BSD-systems

Hi, on BSD systems like OpenBSD, NetBSD, FreeBSD and Dragonfly you have to call 'ldconfig' with the option '-m'. Otherwise you overwrite its configured directory search path.

To reproduce this do:


1.       Get e.g. OpenBSD

2.       # ldconfig -r

/var/run/ld.so.hints:

        search directories: /usr/lib:/usr/X11R6/lib:/usr/local/lib

        0:-lm.5.2 => /usr/lib/libm.so.5.2

        1:-lmenu.4.0 => /usr/lib/libmenu.so.4.0

        ...

        150:-lXdmcp.10.0 => /usr/X11R6/lib/libXdmcp.so.10.0

3.       configure and make install of zlib

4.       # ldconfig -r

/var/run/ld.so.hints:

        search directories: /usr/lib

        0:-lm.5.2 => /usr/lib/libm.so.5.2

        1:-lmenu.4.0 => /usr/lib/libmenu.so.4.0

        ...

        40:-lz.4.1 => /usr/lib/libz.so.4.1

I have attached the patch for zlib-1.2.5. You can view it online here: http://bit.ly/9yYWz1
