since this commit i see two new symbols in aarch64 libstdc++ that were not
there before:
$ nm -D libstdc++.so.6.0.25 | grep call_once
0000000000095e70 W _ZZSt9call_onceIMSt6threadFvvEJSt17reference_wrapperIS0_EEEvRSt9once_flagOT_DpOT0_ENKUlvE0_clEv
0000000000095d10 W
_ZZSt9call_onceIMSt6threadFvvEJSt17reference_wrapperIS0_EEEvRSt9once_flagOT_DpOT0_ENUlvE0_4_FUNEv
this makes the aarch64 libstdc++ abi tests fail.
curiously only happens when native ld is used, not when cross ld.
will debug this further, but in case anybody has ideas let me know.
