My library inclusions are: -lstdc++ -lgcc -lc
Order is important on library inclusions unless you use the -( -) grouping
arguments. I know that memcpy and sprintf would be in libc, so if they
are being pulled in by libgcc, libstdc++ or libsupc++, that would be a problem
with your current commands.

I'm also curious... you use -mthumb-interwork, but you are not specifying
-mthumb for your c/c++ compilation. This will set the interwork flag, but
compile ARM. (OK to do, just not sure it's what you wanted.)
