Closed as fixed for 4.7 Milestone.

Initially I intended to add a -fprogmem-sections command line option that works
similar but independent to -fdata-section.  That way data sections could be
used and strings in progmem merged.  However, I did not find a straight forward
way without cluttering avr BE with lots of code from varasm.c.  Thus, for now,
there is no -fprogmem-sections, i.e. progmem-sections are in sync with
data-sections and you have to decide wether you prefer string merging or fine
grained sections.
