Log Message:
make(1): run tests in an almost empty, controlled environment

Several of the tests use simple variable names that might be influenced
by environment variables of the same name.  Especially the tests for the
?= variable assignment operator need an empty environment to start with,
to produce reliable results.

The PATH must be in the base environment since several tests depend on
the usual tools like echo(1), sleep(1), grep(1).  Setting the PATH to a
fixed value would have made it impossible to run the tests in a custom
environment that don't have a /bin directory.  It's the user's
responsibility to provide a sane PATH.
