[oe] [meta-qt5][PATCH v2 1/1] nativesdk-qtbase: make it possible to keep additional libraries

[Anders Darander]

In some usecases for the nativesdk, you might need some build tools that are built upon Qt5. This means
that we're having a need to keep more of the libraries build by nativsdk-qtbase. This patch adds the
infrastructure to support that
