macOS ar doesn't support @ syntax (#22146)

Browse Source 
When the linker command line is long, Nim compiler generates a file for
passing the linker arguments. On `macOS`, that mechanism fails as the
`@` syntax is not supported by `ar`. Use `xargs` instead to pass the
linker arguments file.

(cherry picked from commit c6c85f84db)
