Seems like the cross-compiled libstdc++.so is missing the pthread symbol.
Something like the following will help you check if that's the case.

1) setup your platforms so the custom DSO's are detected. For example
$export LD_LIBRARY_PATH=/home/piotro/minimyth-dev/images/build/usr/lib/...
2) using the correct ldd issue:
$ldd -r
/home/piotro/minimyth-dev/images/build/usr/lib/gcc/x86_64-minimyth-linux-gnu/5.3.0/libstdc++.so

If you see "undefined symbol: ..." then something's funny in your setup.

Can you check with the libstdc++.so authors that they use "-no-undefined
-Wl,--no-undefined" to the LDFLAGS. It will flag issues as the binary is
linked.
