Here's a patch to add --enable-dso option. Default is to disable DSO.
If both --enable-dso and --disable-shared is present, it prints
warning. It might be better to bomb out instead of warning. You can
change it to whatever you like.

Note that this patch does not solve make check problem with shared
library build. See ldd outputs below. Still, libsvn_ra_dav and
libneon cannot be found. Libtool 1.3.5 doesn't seem to be able to add
dependencies to indirectly linked libraries. (libneon and libsvn_ra_dav
are pulled from libsvn_ra's dependency). I'll try with autconf 2.52
and libtool 1.4 later. I modified build system so that Subversion can
be build with autoconf 2.52 and libtool 1.4 or autoconf 2.13 and
libtool 1.3.5. I didn't have problem to build apr with autoconf 2.52
and libtool 1.4b from Debian sid. I'll send the patch tomorrow since
it might not apply cleanly after applying this and my following patch.

I don't know why libsvn_ra_local is statically linked to libsvn_ra.
Perhaps someone who knows build system better than me can explain it.
