So far only a per thread canary in the TLS block is supported on SystemZ. [This patch for GCC](https://gcc.gnu.org/pipermail/gcc-patches/2025-July/689232.html) adds support for a global canary, too. For this the new option `-mstack-protector-guard={global,tls}` is added which defaults to tls. As described in the patch, also option `-mstack-protector-guard-record` is added. More details are in the commit message.
