Was there a test mass rebuild? If so, how many packages need fixes? I
got bitten by this just now and it would have been nice to fix the
problems upstream before Fedora rebuilds just started failing.

Replying to myself, trying to fix it (by adding the "missing" private
library to the plugins) and rebuilding I triggered a gcc bug on i386:

*** WARNING *** there are active plugins, do not report this as a bug
unless you can reproduce it without enabling any plugins.

../src/fu-device-locker.c: In function 'fu_device_locker_class_intern_init':

ix86_expand_prologue, at config/i386/i386.c:14572
  G_DEFINE_TYPE (FuDeviceLocker, fu_device_locker, G_TYPE_OBJECT)

Yes, this is: https://bugzilla.redhat.com/show_bug.cgi?id=1538648

I can perhaps put a workaround in redhat-rpm-config, which should make it much less likely that this compiler bug is encountered. Rebuilding gcc takes 15+ hours, unfortunately, and untagging it will only revert to a version which miscompiles OpenSSH and RPM. 8-(

Thanks,
Florian
