DS: Can now build binaries via our "configure/make" build system.

Conversion of the old build system is incomplete. Binaries created
using this new build system support most likely will not run!
More work is needed, but the work done so far should be enough
to get basic NDS support on our buildbot working.

+# This does not currently take care of some things:
+# * It does not #define DS_BUILD_A etc. -- most uses of that should be
+#   eliminated, though. Only usage should be for selecting the default config
+#   file (and for that we should really rather allow overriding the value of
+#   DEFAULT_CONFIG_FILE).
+#   There are a few game specific hacks which are currently controlled by this,
+#   too; we need to investigate those.
+# * It does not currently adjust the logo. Ideally, if we ever get real plugin
+#   support, that should be necessary anymore anyway.
