This is for GCC 11.3.0-4, GNU make 4.3.

Kind regards,

It's a mixture of gnu-efi and own issue. For gnu-efi, I've discussed it
with Debian folks and pushed an upstream fix proposal:

https://sourceforge.net/p/gnu-efi/mailman/message/37684742/

If that is not taken fast enough, we may need to apply a workaround
suggested in

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1013341

For the own stuff, similar changes are needed. But let's wait for any
gnu-efi reaction first.

Thanks for reporting!
Jan

With [1] and [2], we should be fully fine again.
