I doubt it.  :)  ld -r and sections groups are difficult to handle
correctly.  The problem is what to do with sections that have the same
name as sections belonging to the group.  Normally, ld -r would merge
such sections, leading to other sections incorrectly becoming part of
the group.  We need to stop that happening, which could be done easily
enough by modifying unique_section_p.  I'll take a look at that.

Meanwhile, I guess your patch is OK.
