dev-lang/go: 1.14: check running kernel version before compiling Compilation will fail if the host is running certain versions of the Linux kernel with the message: runtime: mlock of signal stack failed: 12 Note from williamh: The original pr checked for kernel versions not listed in the upstream issue, so I reworked it. Also, it used pkg_setup instead of pkg_pretend for the checks.
