Notification message levels are too high

Hi,

Warnings are generally for the purpose of alerting people to the fact
that something correctable leaves the opportunity for errors or
hidden problems.  The string, "warning" draws peoples attention to
it.  In libtool's case, every warning is unavoidable and simply
notifications about one thing or another.  And, of course, this
is all the result of automated build rules that few have any
control over anyway.  So, please consider using "notice" instead
of "warning".  Thank you!  :)

Cheers - Bruce
