Akim Demaille d87c8ac79a tests: disable GCC7 warnings for some tests ...

With GCC7 we have warnings (false positive):

    x8.c: In function 'x8_parse':
    x8.c:1233:16: error: 'yylval' may be used uninitialized in this function [-Werror=maybe-uninitialized]
             yylval = *yypushed_val;
             ~~~~~~~^~~~~~~~~~~~~~~
    x8.c: In function 'x8_pull_parse':
    x8.c:1233:16: error: 'yylval' may be used uninitialized in this function [-Werror=maybe-uninitialized]
             yylval = *yypushed_val;
             ~~~~~~~^~~~~~~~~~~~~~~
