Subject: make: fix test for empty command in inference rule

Commit e90345c10 (make: allow empty commands) changed how empty
commands are handled.  This broke the POSIX mode test for
inference rules of the form:

   rule: ;

Adjust the setting of 'semicolon_cmd' to the new reality.

Adds 16-32 bytes.
