That depends on many factors.  There are so many different use cases.
For example: if you install your library, and the relative path was
pointing in the build tree, it will be nonsensical.  But even earlier,
within libtool, there'll be issues when comparing paths.

All in all, if you use it with a library that will be installed and
used by third parties, you are potentially breaking functionality for
them, too.  So please don't do it; you won't be the one working on
bugs reported by those third parties against libtool on its mailing
lists because of this change, and we have enough troubles hunting
down elswhere-induced failures already.
