these symbols should be defined in libgcc_s.so.1
which is linked to c++ code by gcc.
sounds like a gcc toolchain issue, if you cannot
figure it out then post
echo 'int main(){}' |g++ -xc++ -
readelf -ld ./a.out
strace /lib/ld-musl-*.so.1 ./a.out
readelf -d /lib/libstdc++.so.6
readelf -aW /lib/libstdc++.so.6 |grep Unwind
readelf -aW /lib/libgcc_s.so.1 |grep Unwind
