+# libtool tries to abstract away the difference between static libraries

+# symbols, or duplicate symbols.  Either way, it will fail to link your
+# executable.
+#
+# So, our workaround: don't pass any .la libraries to libtool/ld when
+# linking a convenience library, but then run a post-libtool command to
+# insert them into the .la file's dependency_libs. This uses the
+# emptiness of lt.lib.rpath to determine if a library is a static
