Hari,
   Does the binutils on pico understand dwarf3/dwarf4? We ran into
breakage of the bootstrap on darwin...

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41405

due to r151815 which was based on the assumption that all
of the targets could handle dwarf3/dwarf4 instructions.
If not, a proposed patch for a -gstrict-dwarf option is
being worked on there.
