That is, option is dependent on

options         EFIRT                   # EFI Runtime Services support

The ipmi(4) is broken by this too :( The problem is due to the commit 4cfd4d54822bae9794558c988bb59ca9039e9feb (cherry-picked from commit a29bff7a5216bd5f4a76228788e7eacf235004de).

The simplest temporary work-around is to remove the line `#define ARCH_MAY_USE_EFI` in `sys/amd64/include/efi.h` (or `sys/arm64/include/efi.h` -- the i386 is not affected for some reason). Or -- change the `#define` to `#undef`...
