macOS: some of the .prl files have lost the actual filename

5.12 snapshot on staging server, id 5.12.0-201809071645. Install macOS binaries, see the .prl files on 5.12.0/clang_64/lib/ most of the look fine but few are missing:

clang_64/lib/QtQuickTemplates2.framework/QtQuickTemplates2_debug.prl

clang_64/lib/QtQuickTemplates2.framework/QtQuickTemplates2.prl

clang_64/lib/QtQuickControls2.framework/QtQuickControls2.prl

clang_64/lib/QtDataVisualization.framework/QtDataVisualization_debug.prl

clang_64/lib/QtDataVisualization.framework/QtDataVisualization.prl

clang_64/lib/QtPurchasing.framework/QtPurchasing_debug.prl

clang_64/lib/QtPurchasing.framework/QtPurchasing.prl

When I opened the binary content archive for QtPurchasing which is exported from coin, the archive seems to contain a file called '.prl' and the QtPurchasing_debug.prl and QtPurchasing.prl are not there.

Previous snapshot (5.12.0-201808310416) had all above mentioned .prl files.
