[yocto] u-boot recipe: Missing dependencies

I just did it that way for the moment since I wanted to circumvent merge
conflicts when I upgrade the underlying recipes from openembedded.

I thought any Yocto native binaries built are in the PATH automatically.

to fix this/do it correctly?

I put now some patches in ordered manner on top of the original recipes 
from
openembedded.
However, before sending I would like to fix two issues so the recipes 
can go
into mainline immediately.

1.) I am working w/ -morty Yocto branch at the moment. The 'u-boot.inc' 
from
     openembedded does not work w/ -morty.
     I get the following error "AttributeError: module 'bb.utils' has no
     attribute 'filter'". Building w/ the original -morty 'u-boot.inc' 
works.
2.) There is an issue w/ the U-Boot build system that it needs the 
"libgcc.a"
     from the local host system [1]. I circumvented this by checking in 
my
     "libgcc.a" and patching the U-Boot makefile accordingly. This must 
be
     fixed in U-boot.
