No. First, ld.so may search stuff libtool scripts are not aware of.  Second,
ld.so.conf may not have been modified yet at package build time.  Using
runtime data to compile packages has too many caveats to be done lightly. At
the very best, it fucks up crosscompilation scenarios.  Third, trying to be
too clever results in stupid tools that cannot be told to do the right thing
when you know better.

FYI libtool has a terrible past record on rpath handling. Many of our
porters hate libtool with vengeance (or worse), and not many people I've
talked to that are downstream for libtool-using packages like it either.

So, *please* don't overengineer it. Just give us a --without-rpath switch
that actually works, without any clever tricks that are fated to bring even
more pain and suffering to Earth.
