How has this ever worked?

libnotmuch.so links to many things, fortunately when linking Ruby's
notmuch.so binding to libnotmuch.so.3 all those dependencies are
resolved for us, but when you link to libnotmuch.a you need notmuch.so
to link against all those dependencies.

This is triggering cryptic errors such as:

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require':
foo/notmuch.so: undefined symbol:
_ZTVN10__cxxabiv117__class_type_infoE - foo/notmuch.so (LoadError)

Presumably because not even libstdc++.so is linked.

I don't see how this patch could be fixed properly easily, and it was
labeled as a hack, and I didn't like it in the first place anyway, so
I'm going to revert it by tomorrow if I don't hear any good reason not
to.

I also suggest making a brown-paper-bag release 0.13.1 because 0.13
has completely unusable Ruby bindings; there's just no way to compile
them and make them work.

Cheers.
