> [Darwin, config] Arrange for ld64 to be detected as Darwin's linker.
> 
>  This is an initial patch in a series that converts Darwin's configury
>  to detect ld64 features, rather than the current process of hard-coding
>  them on target system version.
> 
>  A ld64-compatible linker is currently required and assumed by Darwin.
>  If a DEFAULT_LINKER is set via --with-ld= then this will be tested to
>  see if it is ld64.
> 
>  The ld64 version is determined for the chosen ld and this is exported for
>  use in setting a default value for -mtarget-linker (needed for run-time
>  code-gen changes to section choices).
>  The support for -rdynamic is converted to be detected at config time, or
>  by the ld64 version if that is found.

The change breaks bootstrap on hppa64-*-*.
