Could you strace it, to see if strace decodes it are ‘kexec_file_load’?
For example like this:

  ./pre-inst-env strace -e kexec_file_load \
    guile -c '(use-modules (guix build syscalls)) (kexec-load-file (open-fdes "/dev/null" O_RDONLY) (open-fdes "/dev/null" O_RDONLY) "")'

38 is ENOSYS (“Function not implemented”), not ERANGE.  This could mean
that kexec support is missing in this kernel.

Thanks,
Ludo’.
