clr.alljits subset fails cross-compiling for linux-x86 on linux-x64 #68044
Description
Description
Cross-compiling the clr.alljits subset for linux-x86 on linux-x64 fails.
The issue seems to be related to building the win-x86 jit as commenting out this line lets the build succeed:
runtime/src/coreclr/jit/CMakeLists.txt
Line 595 in 73665cc
I think the solution might be to change TARGET_UNIX to HOST_UNIX here:
runtime/src/coreclr/inc/clrnt.h
Line 836 in 57bfe47
Reproduction Steps
Checkout repo on ubuntu 20.04, build with
./eng/common/cross/build-rootfs.sh x86
./eng/build.sh -ci -c Release -cross -os Linux -arch x86 -subset clr.alljits
Expected behavior
Build succeeds
Actual behavior
Build fails with the error

Regression?
This built for .NET 5.0.3 (though the resulting product didn't function).
I think the regression may have been in #41126 but I'm not sure about this.
The build fails in .NET 6.0.3 also.
Known Workarounds
I think the solution might be to change TARGET_UNIX to HOST_UNIX here:
