Note that this patch only addresses the problem for the n450, and it
would remain on the atom-pc. If we don't want to take Patch B, then we
would need another solution for atom-pc. The only thing that comes to
mind would be to add the above to the core gtk+ recipe in the form:
#-fomit-frame-pointer in default FULL_OPTIMIZATION will cause
matchbox-panel segfault on atom-pc
FULL_OPTIMIZATION_atom-pc = "-fexpensive-optimizations
-frename-registers -O2 -ggdb -feliminate-unused-debug-types"
Thoughts?
