configure: fix symver support checks
The versioned test symbols must be external, so move them into the
prologue, otherwise GCC 9.3 (at least) reports "Error: invalid attempt
to declare external version name as default in symbol `f@@VER2'".
Also suppress warnings about missing prototypes and return
statements for these test functions.
