Well, it seems to be working now - mostly.
The fix was to write a new gpt label, create all the partitions and build a
new system: no use of earlier packages. User data came from backups.
Meanwhile, I used bootctl and efibootmgr to create and delete boot entries in
the efi data until I finished up with this arrangement:
# bootctl

Note 1: I still can't 'bootctl install' without causing the damage I've
described already. The system does boot though.
Note 2: I've tried to change this with 'efibootmgr -b 00 -L "Gentoo Linux"',
to no avail. It does nothing I can see.
Note 3: This title comes from the file named two lines later; it has nothing
to do with the Title of Note 2.
Furthermore, when the default entry starts, I see 'SHA256 verified' in the
upper left corner of the EFI BIOS display area, until the kernel takes the
terminal over.
Oh, and I deleted the unused directory (by me) /boot/EFI/systemd.
So: solved, mostly. I still don't know what has changed though.
