Subject: [PATCH 1/2] depends: enable lto support for Apple's ld64

Note that this does not _enable_ lto by default in any way, only hooks up the
machinery for -flto to work correctly.

enable-lto-support is explicitly used for pinned-clang because we know it
works. It is neither enabled nor disabled in the external clang case so that
it can be auto-detected.
