Output section type (READONLY)

So basically what you are saying is that if a input section is assigned
to an output sections with incompatible attributes (presumably because of a
linker script declaration) then the linker should issue a warning message,
yes ?

By extension then, this feature should cover not just the readonly section
attribute, but the NOLOAD attribute as well.

This sounds like it might be an interesting feature to implement for someone
looking to gain experience with the binutils.
