SIGSTKSZ and MINSIGSTKSZ are moving away from being constants. SIGSTKSZ is now a call to sysconf().
This was causing a build error building our tests, which is fixed using the suggestion from Stanislaw Kardach.
For the core, we eliminate the constants to avoid invoking libc. We look for AT_MINSIGSTKSIZE in our existing auxv search code and if not found we fall back to a hardcoded value.
