AC_SEARCH_LIBS is the recommended macro for these checks, unfortunately, we use AC_CHECK_LIB instead, and even AC_CHECK_FUNC, when only one AC_SEARCH_LIBS would be enough. This wrapper macro is used much like PKG_CHECK_MODULES, as it defines (and AC_SUBST) the PREFIX_LIBS variable itself. It also avoids adding unnecessary stuff to LIBS.
