For a reason I didn't figure out, the build is broken :

  MKIMAGE
  CC [M]  fs/ecryptfs/read_write.o
  CC [M]  fs/ecryptfs/crypto.o
  CC      lib/kasprintf.o
  CC [M]  net/bluetooth/mgmt.o
  CC      kernel/compat.o

Invalid CPU Type - valid names are: alpha, arm, x86, ia64, m68k, microblaze, mips, mips64, nios2, powerpc, ppc, s390, sh, sparc, sparc64, blackfin, avr32, nds32, or1k, sandbox
Usage: mkimage -l image
          -l ==> list image header information
       mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image
          -A ==> set architecture to 'arch'
          -O ==> set operating system to 'os'
          -T ==> set image type to 'type'
          -C ==> set compression type 'comp'
          -a ==> set load address to 'addr' (hex)
          -e ==> set entry point to 'ep' (hex)   
          -n ==> set image name to 'name'
          -d ==> use image data from 'datafile'
          -x ==> set XIP (execute in place)
       mkimage [-D dtc_options] [-f fit-image.its|-F] fit-image
          -D => set options for device tree compiler
          -f => input filename for FIT source
Signing / verified boot not supported (CONFIG_FIT_SIGNATURE undefined)
       mkimage -V ==> print version information and exit

It looks like mkimage choking with some arguments, but, from what I know, we didn't changed anything on Armbian side. So, maybe something that Icenowy introduced in her branch ...

 

EDIT : Oh ! I've found something on Armbian side : the *.scr are missing ...

What is missing? It's building here 

On my side, none of the A64/H5 are building since 24 hours.

 

Resolved with the help of Zador : mkimage version too old, but problem appeared only today ...
