Subject: [PATCH 13/14] [MC][test] Change ELF/uleb-ehtable.s Mach-O to use
 private symbols in .uleb128 for label differences

On Mach-O, `.uleb128 A-B` where A and B are separated by a non-private symbol is invalid
(see D153167).

(cherry picked from commit 0a89bda4a8b756a00985e0965f7686b5ceb43295)
