package/openldap: fix static linking wih atomics

openldap uses its own libtool, static build with atomic fails with our
patches since February 6th 2019 on:

/bin/sh ../../libtool --mode=link /home/buildroot/autobuild/run/instance-0/output/host/bin/or1k-linux-gcc -static -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os   -static  -static   -o idtest idtest.o liblber.la ../../libraries/liblutil/liblutil.a -L/home/buildroot/autobuild/run/instance-0/output/host/bin/../or1k-buildroot-linux-uclibc/sysroot/usr/lib -lssl -L/home/buildroot/autobuild/run/instance-0/output/host/bin/../or1k-buildroot-linux-uclibc/sysroot/usr/lib -lz -pthread -latomic -lcrypto -lz -pthread -latomic
