This sounds like the simplest idea so far, plus it may even be of use to
other situations portably.

Keith, could you confirm that this would be enough for your needs, when
given as install mode switch?  Current idea would be to have it install
the first name from library_names only, do not delete the symlinks nor
create new ones, do not install the .la file.

Or do you also need to prevent creating the symlinks in the build tree
(below $builddir/.libs/), maybe because you actually build all three
library major versions in the same directory?  Then we'd need to do
something at link mode.

Cheers,
Ralf
