Okay, I tested that change on normal x86_64 with the static flag, and it 
does seem to work, so I have no problem with your change.

Are you sure you need a -static link flag for embedded? I was talking to 
another arm developer who also cross compiles but doesn't need it.

Also, the reason I asked whether something was missing, is that the text 
to your patch contains "Subject: [PATCH 2/2] bugfix: Support static 
linking(-static) with"

so I was wondering where Patch 1/2 was.

Thanks.
