[PATCH] Behave correctly when users specify SWIG binary instead of SWIG directory as configure option

Occasionally, users will forget to read instructions. When they do,
it's helpful for us to be as forgiving as we can.

In our configure documentation, we ask users to specify
--with-swig=PATH. Currently, when users specify the path to "swig" as
the path to the SWIG binary, the build fails with an error message
that is difficult to understand. This patch makes SWIG build correctly
in that situation, and it therefore will make the Subversion build
process just a little bit more user-friendly.
