Sure, no problem.

But building ldc 0.17.4 I get phobos datetime test failures.
Not sure why - because as you've written it, ctest shouldn't have tested phobos.

Also, ldc 1.7 does use phobos.  I determined this as follows:
I removed phobos-src from ldc-bootstrap, then used the resulting ldc-bootstrap
to build ldc 1.7.  It failed.  I tried to excise phobos users from it but gave up.

(Even ldc 1.1 used std.datetime during building)

So I reverted the "check" phase.

Also, ldc 1.7.0 test failure on the X200 laptop:

Which is understandable because the X200 laptop doesn't have AVX.

It's building another round now - let's see.
