解决编译报错：c-stack.c:55:26: error: missing binary operator before token “(“

在使用ubuntu22编译openwrt 19时报错：c-stack.c:55:26: error: missing binary operator before token "(" 55 | #elif HAVE_LIBSIGSEGV && SIGSTKSZ < 16384

解决办法：(使用补丁)

在openwrt目录下：

cd tools/m4/patches
wget https://raw.githubusercontent.com/keyfour/openwrt/2722d51c5cf6a296b8ecf7ae09e46690403a6c3d/tools/m4/patches/011-fix-sigstksz.patch
