[Bug-dejagnu] make-style variable assignment broken in runtest 1.4.2

[Per Cederqvist]

The make-style variable assignment of runtest appears to be broken in
the 1.4.2 release.  The enclosed patch fixes the problem.

Repeat-by:

        runtest --tool something VARIABLE=value

You will get an "Illegal Argument" error message.
