not only on Arch, this fix is also required on any EL9.1 Distro

Awesome! It doesn't seem to break anything with RHEL7.

Thank you for this. Great to know that RV can be built on other Linux distros.

Regarding building on Arch Linux, this is the only fix I was able to provide. The other errors I found are mentioned in #15 and @marcomeyerVFX seems to have found the fixes.
