target/hexagon: suppress unused variable warning
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`.
