Remove the build-key from the plugin verification data
The build-key is an old mechanism to work around binary
incompatibilities in GCC 3.x versions. Modern GCC has not broken binary
compatibility since 3.4, making this mechanism obsolete.
The cache value stored now only includes Qt version, the debug/release
boolean, and the last modified time for the plugin. Old 4-value keys
will be replaced with new keys as the plugins are reloaded the first
time.
This also removes QLibraryInfo::buildKey(), which is a source-incompatible
change.
The UNIX and Windows configure tools have been updated to stop
outputting the QT_BUILD_KEY preprocessor directive.
