Our 10.4 system is using gcc (for now).

when we compile the devel/binutils port, we get a failure with a bunch 
of these errors:


`_ZTSN12_GLOBAL__N_110Stub_tableILi64ELb1EEE' referenced in section 
`.rodata' of aarch64.o: defined in discarded section 
`.rodata._ZTSN12_GLOBAL__N_110Stub_tableILi64ELb1EEE[_ZTSN12_GLOBAL__N_110Stub_tableILi64ELb1EEE]' 
of aarch64.o

I managed to defeat these one before but I forget how.

possibly the answer is to use clang/clang++ for this item but I tried 
defining CC and CXX  to clang/clang++ in the Makefile but that didn't 
seem to help

there's probably a USE_CLANG option or something that I haven't seen.
