[Interest] Building Qt for Android with SSL (ie. how to avoid QT_NO_SSL define)

[Kari Pahula]

Replying to myself: I figured it out.  I'm documenting this for
posterity's sake.

I found the right clues at https://bugreports.qt.io/browse/QTBUG-96663

First off, Qt's build isn't idempotent.  The variables and flags have
to be right on the first try or it will forever get the config with no
OpenSSL from some cache instead.  It has to be with a freshly
extracted dir.

The right syntax for this was:

-openssl-runtime yes -- -DOPENSSL_ROOT_DIR=$SSL_PREFIX -DOPENSSL_INCLUDE_DIR=$SSL_PREFIX/include
