-Subject: [PATCH] [test] Fix tools/gold/X86/comdat-nodeduplicate.ll on non-X86
- hosts
-
-When running this test on an aarch64 machine, it fails:
-
-```
-/usr/bin/ld.gold: error: .../test/tools/gold/X86/Output/comdat-nodeduplicate.ll.tmp/ab.lto.o: incompatible target
-```
-
-Specify the elf_x86_64 emulation as all of the other gold plugin tests
-do.

-Reviewed By: MaskRay
