Backport needed for ARM32 Year 2038 issue fix to .Net 8.x from .Net 9.0

[satmandu]

Description

Using .Net 9 RC2 fixes the issues with SSL certificate validation failing on the arm32 Github Runner, but using .Net 8.0 (which the runner is about to move to) does not solve the problem.

My patched version of the Github Runner at satmandu/runner#1 successfully authenticates to Github, whereas building from top of tree (which has just moved to .Net 8.0 from .Net 6.0, still has the same breakage.)

See actions/runner#3505
#101444
#96460
#102410

Reproduction Steps

The current arm github runner fails to authenticate to GitHub. See actions/runner#3505

Expected behavior

The arm32 github runner should not have ssl certificate validation issues with Github.

Actual behavior

Logs are at actions/runner#3505

This was discussed more in depth here: dotnet/core#9285

In short, it was intended that .NET 8 remains incompatible with on Linux Arm32 that uses 64-bit time. That means .NET 8 will not run on Ubuntu 24.04 (for example) on an ARM32 system.

As for "why" this cannot be back ported, it is a breaking change. It requires a glibc version increase to 2.34.

Thanks @vcsjones for the link to the conversation and the explanation. With .Net 9 releasing next month the Github Runner folks consider moving to .Net 9 for the arm runner when being run on newer ubuntu releases...
