Reference to stub in libgcc.a

What is the *exact* command line with which you are invoking
arm-elf-ld ?  (If you are running the linker from gcc then try adding
the -v command line switch).

You may find that adding the --trace-symbol=_call_via_r3 switch you
can find out if the library is being loaded at all.
