Fixed breakage of NOSHARED worlds in previous commit. -lreadline was

added but not its postrequisite -ltermcap.

Fixed breakage of DPADD in previous commit.  ${LIBREADLINE} was misspelled
-lreadline.  This should have been fatal since there is no file named
-lreadline, but it worked because of an undcumented bugfeature in make(1)
(or its configuration files): missing source files named -l* are silently
assumed to be up to date libraries.  `make checkdpadd' also fails to detect
this error.
