Description: Change LDAP C SDK version to 6
Fix Description: Change the version to major 6, minor 0, and submin/patch 0. The change is in various places in the build makefiles and header files. The shared lib suffix is now 60 (from 50).
In a somewhat unrelated change, the configure script had to change to allow
building with the RPM spec %configure macro on rhel/fedora. That macro
defines --host, --build, and --target, and defines --host different than
--target. This caused configure to think it was doing a cross compilation.
Instead, the correct cross compilation trigger is if --host is specified and
it is different than --build. However, the mozilla builds expect to be able
to pass in --host different than --target, so all of these different
combinations had to be accomodated.
