[llvm] [dbginfo-tests] Use -march instead of -arch to avoid getting an error for non-darwin targets. (PR #98977)

[Wolfgang Pieb via llvm-commits]

https://github.com/wolfy1961 created https://github.com/llvm/llvm-project/pull/98977

Our upstream buildbot is getting an error with the -arch option on Ubuntu-22. Not sure why this isn't showing up anywhere else. Using -march instead, but is that OK with you @adrian-prantl ?
