[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.
