This could be problematic if any of the functions returns a string containing illegal filename characters (e.g. /).
We could do further filtering, or once such an implementation is identified, we could map the values it returns to sane words.
Anyway, the point here is to add the machine type (uname -m) to be able to have in the same NFS-mounted home directory both SBCL-0.8.14.9-X86 and SBCL-0.8.14.9-PowerPC.
