5.15.2 MSVC2019/MinGW static build, some tools not compiled

Qt5.15.2 source package, build the whole src archive in static mode using MSVC2019 x64, configure options (skipping webengine, -view, qt3d and quick3d just to save build time):
(-no-sql-mysql -no-sql-sqlite -no-sql-odbc -no-sql-psql -confirm-license -nomake tests -verbose -release -nomake examples -qt-zlib -commercial -static -no-compile-examples -skip qtwebengine -skip qtwebview -skip qt3d -skip qtquick3d -prefix my_path_here/qtbase)
Following tools doesn't get compiled:
\qtbase\bin\qdoc.exe
\qtbase\include\qthelp
\qtbase\lib\qt5help.lib
\qtbase\lib\qt5help.prl
\qtbase\plugins\sceneparsers
\qtbase\bin\qmlplugindump.exe
\qtbase\bin\qmlscene.exe
\qtbase\bin\assistant.exe
\qtbase\bin\qhelpgenerator.exe
 
I'm not sure do they support static build, so should be checked.
Edit: same issue with MSVC2019 x86 and MinGW. Not a regression, same executables not compiled with 5.15.1 sources either.

Edit2: I don't have the original build log saved anymore, the attached log is from re-run where the '-skip qtquick3d' was removed from configure options, don't know if it's any help...
