Subject: build: disable kernel stack protector support for i386/x86_64
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=bf82deff7069599c9f130f5bb0222acd171fd19d;p=librecmc%2Flibrecmc.git

build: disable kernel stack protector support for i386/x86_64

When stack protector support is disabled in libc (always the case for
!musl), gcc assumes that it needs to use __stack_chk_guard for the stack
canary.
This causes kernel build errors, because the kernel is only set up to
handle TLS stack canaries.
