Cmucl can't load test files after moving tests to subdirectories
When running the makefile to run the tests with cmucl, the tests won't load because cmucl can't find "symbols/load.lsp". This is because this file sets
*load-pathname*. In this case, cmucl sets
*load-pathname* to #P"", which is valid, I think, if unexpected. Then the files in the
symboldirectory can't be loaded because the actual current directory is still the main ansi-test directory.
