build: Remove substitution of *_OBJ variables Remove substitution of *_OBJ variables (e.g. POPT_OBJ or PCRE_OBJ) from configure scripts as they don't seem to be set or used by anything. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

BUILD: Explicitly link libsss_ad.so with sasl libs If openldap is not built with sasl support libsss_ad.so will not be linked with libsasl2 although sasl_client_init is called by function ad_sasl_initialize.
