[Automake-NG] [FYI] [ng] check: use few more GNU make capabilities

[Stefano Lattarini]

We can do so now that the 'parallel-tests.am' file is now
processed "almost verbatim" by Automake.

* lib/am/parallel-tests.am (check-TESTS): Here, use "ifeq" to check
whether $(AM_LAZY_CHECK) is "yes".  This removes the need for ...
(am__remove_if_not_lazy_check): ... this variable, which has thus
been removed.
