build: Add (and use) an AC_SEARCH_LIBS wrapper
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.
