From glibc ≥ ~2.34 SIGSTKSZ is no longer constexpr

Relatively easy to repro if you build on docker. Builds on ubuntu 20.04 for example will work fine. Builds on 24.04 have the issue

FROM ubuntu:24.04

Currently I'm using a quick hack to get things building just by setting on build:

-DCMAKE_CXX_FLAGS='-DCATCH_CONFIG_NO_POSIX_SIGNALS -DSIGSTKSZ=0'
