That's usually too conservative. CVS Libtool's _LT_LINKER_OPTION takes
empty stderr as success, or a zero diff between a link without and with
the option in question. Mind you though, even this is far from fool-
proof; in fact, there are some known failure cases where compilers or
linkers are just too noisy. (This is also why we haven't suggested the
macro for Autoconf yet.)
