# greenlet ships no 32-bit ARM wheel, so on armv7 it is compiled from source.
# setuptools links the C++ extension with gcc, which leaves libstdc++ out of the
# .so's NEEDED list, and it then crashes at import with an undefined libstdc++
# typeinfo symbol, taking startup down during the DB migration. Add libstdc++ to
# the NEEDED list so the loader pulls it in. Only armv7 is affected; amd64 and
# arm64 use a correctly linked prebuilt wheel.
