[PATCH] gold testsuite: avoid unused private member in undef_symbol.cc

[Roland McGrath]

I'm not sure why this test wasn't just "int foo(void) { return a; }"
anyway.  But this is the minimal change to the status quo that suppresses
the warning about an unused member.

OK for trunk and 2.24?


Thanks,
Roland
