Michael LeMay b915e7d5e3 galileo: Omit exception handling unwind tables
This patch modifies the newlib and Contiki C and C++ compiler flags to
omit exception handling unwind tables (see
http://wiki.dwarfstd.org/index.php?title=Exception_Handling).
Removing these tables saves space in debug builds and has not caused
any readily-apparent functional changes.

Here is the size listing for an example program built without this
patch:
   text	   data	    bss	    dec	    hex	filename
  76002	   1508	  21224	  98734	  181ae	all-timers.galileo

Here is the size listing for the same program with this patch:
   text	   data	    bss	    dec	    hex	filename
  72918	   1508	  21224	  95650	  175a2	all-timers.galileo

The primary motivation for this patch is to help enable UEFI support.
The .eh_frame and .eh_frame_hdr sections that are otherwise generated
are treated as code sections by the EDK2 GenFw program, since they are
read-only alloc sections.  They get grouped with the actual code
sections, ahead of the data sections.  This perturbs symbols and
complicates debugging.
