Sure, but the SONAME still has to be right, so I can't build
libXaw6.so.6.0.1 with SONAME libXaw6.so.6, symlink it to libXaw.so.6 and
expect applications asking for libXaw.so.6 to work.

Which means that with current libtool, I must ask it to build
libXaw.so.6 and then link that to libXaw6.so.6, which I also can't do as
that will trash any libXaw.so when libtool installs the library.

I don't mind getting libtool to build libXaw.so.6, but I can't ask
libtool to *install* a libXaw.la that points at that file.

Thanks for reminding me that the filename is still relevant for
libraries not in ld.so.cache; I'll have to make sure I create the links
at install time. Of course, if we do hack libtool to support alternate
SONAME values, we could also hack it to manage these symlinks for us.
