 # The macOS linker has however an option to explicitly keep those object
 # files, which dsymutil will then find.
 # The catch is that the linker uses sequential numbers for those object
 # files, and doesn't avoid conflicts from multiple linkers running at
 # the same time. So in directories with multiple binaries, object files
 # from the first linked binaries would be overwritten by those of the
 # last linked binary. So we use a subdirectory containing the name of the
 # linked binary.
