Description of problem:
Passing arguments like

 CC="gcc -L/home/gnu/binutils-2.12.1-i686-redhat7-linux-gnu/ld"

to runtest results in an error message:

  Illegal Argument "CC="gcc -L/home/gnu/binutils-2.12.1-i686-redhat7-linux-gnu/ld""

The problem is caused by not checking env. variable like
arguments in the main loop used to parse arguments in
/usr/share/dejagnu/runtest.exp. The attached patch fixes this.

Actual Results:  Error message is produced as described above.

Expected Results:  No such error message should have been generated.
