Hi Ian,

  I have been looking at this PR, trying to find a way to solve it, but I am
hopelessly lost.  So I am asking for some guidance...

  It seems to me that gold parses the KEEP directives and stores them in
Output_section_element_input class, but then it just ignores them.  Then when
Sized_relobj_file runs garbage collection there appears to be no way to connect
the Output_section pointer to the input sections that contributed to it.  So I
guess my question is - when garbage collection occurs, how do I find out if a
particular input section should be KEPT ?
