The fundamental oversight in this proposal is the desire to wanting to
distinguish 64bit and 32bit systems. multilibing actually is about
supporting several ABIs in parallel.

64/32 bit ABIs on Linux actually are a very special case.

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.
