What's the umask of the your uid ? .. or maybe this is
one of those settings that is controlled by bitbake/poky.
But either way, it should just be that the cp is taking
the current umask which is changing the mode to 0744.

One option is to use install to copy the files, since it
allows a specific set of permissions to be set on its
command line.

I haven't looked into this at all, just some thoughts
off the top of my head.

Cheers,

Bruce
