qtbase build error: call to non-'constexpr' function 'long int sysconf(int)'

Trying to build Qt5 with toolchain that is built using yocto Honister. This causes qtbase to fail cause of how new glibc handles MINSIGSTKSZ so that it's no longer compile-time constant.

Here's a link to the error in coin:

I found one project with a similar problem in the opensource world, and here is the commit they fixed it with. They also fixed a few other things it seems in the same commit: https://github.com/OpenImageDenoise/oidn/commit/4180502f326dccd5e46ab67176b53cc800e32f7b

 EDIT: To clarify, this error is due to changes in glibc version 2.34
