I fixed it by removing the whole conditional and simply referencing the .la
file. That is the whole point about libtool 1.4 -- you reference .la files
and it actually works during shared builds.

In libtool 1.3, you cannot reference a .la file if there are dynamic libs
specified inside of it. So... we always went into the .libs directory and
implicitly referred to the .so file directly.

In most cases, where we use -L<dir> -l<lib>, it can/should be replaced by a
direct reference to the .la file. Our berkeley-db.m4 file needs updating for
when it searches the system, it should use a .la if it finds it. The code
block you reference above only uses the .la file for an included "db" dir.
