Right.  There is also value to separate between some libraries which 
use the same ABI but with different run-time behavior.  For example, 
libraries instrumented for profiling could go in a different 
directory.

Some of the available libraries might not even run on the current CPU 
and operating system type, but could be used to create a build which 
runs on a different CPU and operating system type.  OS-X fat binaries 
come to mind.

There is no shortage of reasons to want to put libraries in different 
directories and autoconf/libtool should not stand in the way of 
freedom.
