Presumably this also happens if you do a normal build with -fvia-C, i.e.
it's not specific to building from an HC file bundle?

GHC will act as if -fvia-C is given if -keep-hc-files is given. It
would be nice to update the wiki to say -fvia-C rather than -fasm to
avoid confusion, though.

Note that there is a plan to drop the registerised via-C way of
compiling GHC at some point, so this isn't going to work in the long
term (unless you want to bootstrap via an unregisterised compiler).

Would it not be possible to have a ghc-bin package in OpenBSD, which
contains a precompiled binary that can be used to compile a ghc source
package? I think Gentoo does something like that.

Yup.
