The source line is just


          if (nr_elts > 0 && (ch->szB - sizeof(SizeT)) % nr_elts == 0) {

and I presume that is the modulus operator that is bringing in 
__aeabi_uidivmod

According to https://clang.llvm.org/docs/ClangCommandLineReference.html 
there may be a clang runtime library libclang_rt.builtins.*.a

If you have that could you try linking with it (instead of libgcc.a)?
