[llvm] [orc-rt] Generalize testcases for different target archs (PR #222629)

[Lang Hames via llvm-commits]

https://github.com/lhames created https://github.com/llvm/llvm-project/pull/222629

Drop the hard-coded archs from the check-rt-process-info testcases. Instead, check against an arch value derived from the build's target triple.

Subject: [PATCH] [orc-rt] Generalize testcases for different target archs

Drop the hard-coded archs from the check-rt-process-info testcases.
Instead, check against an arch value derived from the build's target
triple.
