within the example OBJDIR (mip64el), the only "*kernspace*" are:

./tests/rump/kernspace/libkernspace.a
(dated 19 Aug 2023)

./tests/rump/kernspace/libkernspace.so.0.0.debug
./tests/rump/kernspace/libkernspace.so.0.0.link
./tests/rump/kernspace/libkernspace.so.0.0
(dated 31 May 2020)

Maybe it's trying to link against one of the "*.so.0.0"?  But they should
be the same date as the "*.a" or not exist if I ran a non-update build.
