 Arnout> Without the -m64, choosing the x86_64 architecture with a Sourcery external
 Arnout> toolchain will result in a 32-bit rootfs.

 Arnout> Also simplified the help text to reflect this change.

 Arnout> v2: Feedback from Thomas
 Arnout> * Less aggressive modification of the help text.
 Arnout> * Make -m64 flag specific for x86_64.

 Arnout> Build-tested only.

You have some whitespace damage here, but otherwise it looks good -
Committed, thanks.
