Attached is a patch that attempts to build the manifest in an inferior.
This fails because manifest->gexp returns a gexp that we can’t get out
of the inferior to pass to build-profile.

So even more of the surrounding code would have to be evaluated in the
inferior.

@Ludo: your patch looks good to me.  It’s a pragmatic, minimally
invasive fix, so thumbs up emoji from me!  Thank you!
