    testsuite: Fix for targets not passing argc/argv [PR116154]

    PRU and other simulator targets do not pass any argv arguments
    to main.  Instead of erroneously relying on argc==0, use a volatile
    variable instead.

    I reverted the fix for PR67947 in r6-3891-g8a18fcf4aa1d5c, and made sure
    that the updated test case still fails for x86_64:

      $ make check-gcc-c RUNTESTFLAGS="dg-torture.exp=pr67947.c"
      ...
      FAIL: gcc.dg/torture/pr67947.c   -O1  execution test
      ...
      # of expected passes            8
      # of unexpected failures        8

    Fix was suggested by Andrew Pinski in PR116154.  Committed as obvious.

    gcc/testsuite/ChangeLog:

            * gcc.dg/torture/pr67947.c: Use volatile variable instead of
            argc.
