I haven't tried 2.20.  It looks as though we may need to add "-ldl" to the 
command line for elf2efi64.  Could you try running

  gcc util/elf2efi.c -I/usr/include -I/usr/include -I/usr/include -idirafter \
    include -L/usr/lib -L/usr/lib -L/usr/lib -lbfd -ldl -liberty -lz \
    -Wl,--no-warn-search-mismatch -DEFI_TARGET_X64 -O2 -o util/elf2efi64

and let me know if it works?  If it does, I'll push a change to the tree.

Thanks,

Michael
