AIX shared libraries in MLB and 1.4

[libtool]

I'm looking over the differences in how shared libraries are built
between MLB and 1.4. Some questions:
  1. Any reason for version_type=linux in 1.4 and not MLB?
  2. Should we sync up shared library names between 1.4 and MLB
     (cf soname_spec below). Shared library names in MLB are
     libfoo.so.o while in 1.4 its libfoo.so.$major.
