Presently, the _SOURCES variable for target `4th' is
`4th_SOURCES'.  No leading underscore.  This seems to comply
with POSIX rules to name Makefile variables.

The question is more about targets that don't start with an
alphanumeric character.  This is probably less frequent, and
maybe it could be solved without changing the canonicalization
rules if we use one of these ideas:
