I don't believe there is.  Autoconf can not depend on libtool, so 
Autoconf should not provide such a macro, but it certainly makes sense 
for libtool to provide a LT_CHECK_LIB as you describe.  A challenge is 
that in libtool 2.0, the libtool script is not generated until the end 
of the configure script run (an `enhancement' in 2.0) so it is not 
available for use.  The macro would need to emulate the operation of 
libtool since libtool is not available yet.
