This patch manually suppresses a warning for an unused variable (yynerrs) emitted by bison.
This warning has been triggered for the first time by clang 15. This patch also disables `-Wextra`, which is not usually adopted in QEMU. However, clang 15 triggers the warning fixed in this patch even in absence of `-Wextra`.
