Indeed. That's probably the reason why libtool doesn't use this flag
on GNU/Linux.
Mark, will you please revert your patch, so that libtool in the GCC
tree works properly on GNU/Linux.

The problem is that the name of the dynamic linker may change across
glibc versions. I'm not sure I want to go down that road in libtool.
-no-undefined is a do-nothing on most platforms, anyway, so I don't
think it's a big deal for it to be a do-nothing on GNU/Linux too.
