Fullhan u-boot proprietary crap

'fh_mkimage' - appears to work in 64-bit Ubuntu 22.04 with lib32z1 package installed. Couldn't get working with patchelf.

        linux-gate.so.1 (0xf7fb8000)
        libc.so.6 => /lib32/libc.so.6 (0xf7d78000)
        /lib/ld-linux.so.2 (0xf7fba000)
------------------------
./fh_mkimage
Usage: ./fh_mkimage -l image
          -l ==> list image header information
       ./fh_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)
       ./fh_mkimage [-D dtc_options] -f fit-image.its fit-image
