configure: Pass -fasynchronous-unwind-tables to the compiler.

On aarch64-linux-gnu, unwind tables aren't emitted by default (contrary to x86_64-linux-gnu), so we must pass the flag (or -funwind-tables) to the compiler to make it generate them. Previously wine just added the flag to the linker options. Signed-off-by: Martin Storsjo <martin@martin.st> Signed-off-by: Alexandre Julliard <julliard@winehq.org>
