Usually something as:
AC_PATH_PROG(FOO_CONFIG, foo-config)
if test -n "$FOO_CONFIG"; then
    AC_DEFINE(HAVE_FOO)
    FOO_LIBS=`$FOO_CONFIG --libs`
    FOO_CFLAGS=`$FOO_CONFIG --cflags`   
fi

You mean encapsulating the previous logic ? You may define it as a m4
macro, as some libs already do for instance.
