I am not sure how, but this patch is causing some failures in poky with
core-image-sato build, it seems that that the args coming from the 
rootfs_install_complementary get goofed up somehow, not sure but I 
bisected down to this patch.

the -poky seems to have a space added so it gets -poky -linux on the 
command line for oe-pkgdata-utils.

Sau!
