When building back-meta with modularized the function mapping_free is not found
during startup of slapd. I used the following connfigure-options:

./configure     --prefix=${PKG_INSTALLROOT} \
                --with-tls \
                --enable-rlookups=yes \
                --enable-dynamic=yes \
                --enable-modules=yes \
                --enable-bdb=mod \
                --enable-dnssrv=mod \
                --enable-ldap=mod \
                --enable-meta=mod \
                --enable-null=yes \
                --enable-passwd=mod \
                --enable-perl=mod \
                --enable-shell=mod

The attached patch takes the function mapping_free from back-ldap and uses it
in back-meta.
