(Perhaps 'payload' should be in $target in the first place.)
Config.lb is used to build several Makefiles and they are in
further subdirectories of target/vendor/board/dir/
It is easy and reliable to use an absolute path to the payload.
Apparently that (in targets/tyan/s4882/Config.lb) is unreliable: I tried 
payload 'grub2' and './grub2' (see below) and if it is this hard for me 
(with 14 years programming experience on mostly Linux) because it is 
undocumented, I would call it easy for few people.  Of course it seems 
like there is also much great work on the project....

PS. I tried the following Config.lb payload paths with 'payload ./grub2' 
and 'payload grub2' (and left out 'fallback' one time for each.)
