Libtool itself understands the content of *.la files.  conceivably you 
can execute libtool from within the configure script to perform tests. 
Autoconf is not going to do this automatically for you though so you 
would not be able to use AC_CHECK_LIB directly.  It *might* be 
possible to make use of AC_CHECK_LIB by temporarily altering the 
definition of CC and LD.

There has always been a bit of an impedance mis-match between autoconf 
and libtool since autoconf does not depend on libtool or know about 
.la files.
