This is different.  Here those strings are actually referenced and can't 
be discarded.  The solution is to mark them so they go in the 
appropriate section as suggested.

It might be worth investigating the addition of a new gcc function 
attribute that provides a replacement section for .data, .rodata, etc. 
in addition to .text, that would apply to data objects created within 
that function.
