Linux arm checked failure is #73247. I have double checked that the leg is actually building with hard fp support (and #ifdef __SOFTFP__ is false).

We use __SOFTFP__ macro in debugger support e.g.

@am11 Any concerns with waiting until upstream takes this?

No concerns (with a but) :)
Just wanted to note that it might be useful for .NET 7 as linux-armv6 is new platform in 7.0 and CLR_CMAKE_HOST_ARCH_ARMV6 is used in libunwind.cmake; as corehost requires coreclr-pal (even for RuntimeFlavor=mono). Though I am not sure if we support (or have CI coverage for) softfp variant with armv6 as the compilation should had failed in the CI. git grep '\-mfpu=' suggests we don't but in places without -mfpu option set, it defaults to toolchain's baseline, so it is unclear if we actually support softfp/-mfpu=none.

Upstream PR is merged.

Issues are #73247 and #73474.
