And do they also have have a line starting with "From " as the first
line? This makes them mbox files. The second "From " makes them mbox
files with multiple messages. Notmuch thinks your MDA (the thing that
made those files) is misconfigured, assuming my guess about the format
is correct.

There is not currently a way to do that. It's not a GMime problem, it's
a design choice of notmuch to avoid parsing multiple message
mbox's. That was originally added as a safety feature, and I think it
should probably stay the default. If someone wants work on adding a
configuration switch I can point them in the right direction.
