    testsuite: tolerate argc==0 [PR126194]

    Some embedded targets set argc to zero when calling main, but then
    pr126194 testcase fails because it uses argc > 0 to enable the code
    that allows the test to pass.  Derive the argc passed to the primary
    LTOed entry point from argc >= 0, so that it isn't a link-time
    constant, but the guarding condition always passes at runtime.
