[oe] [meta-qt5][PATCH] qmake4_base.bbclass: Add staging directory for native builds

[Donald R. Poole, Jr.]

From: "Donald R. Poole, Jr" <donald (dot) poole (at) swri (dot) org>

When building a basic Qt5 native application, the build fails on the do_install task as a result of the  variable being empty. This causes the copy command in the test block to fail because it is trying to copy files from/to itself.
