description:
make(1): make Hash_Table independent from -funsigned-char

This only makes a difference for Hash_Table keys outside the ASCII
character set, and these are barely used in practice, if at all.

The effects of this change can only be seen in debug mode, when printing
the full contents of the variable namespaces.  In this output, the order
of the entries might change.

All other use cases stay the same as before.
