qmake: Fix overlong command lines for static Qt builds on Windows Linker response files for the MinGW and Unix makefile generators are controlled by the variable QMAKE_LINK_OBJECT_MAX. This variable holds a number. If the number of object files passed to the linker exceeds this number, a linker response file containing object file paths is created. This heuristic is extremely imprecise. It doesn't take into account the length of object file names nor the length of $$OBJECTS_DIR. Also, when using a static Qt, a big part of the linker command line are libraries. A relatively small example can fail to link with "The command line is too long" on Windows, even with the object files being in a response file. The MinGW makefile generator already reads the variable QMAKE_RESPONSEFILE_THRESHOLD for compiler response files. Re-use this variable for the linker response file of the Unix and MinGW makefile generators. If QMAKE_RESPONSEFILE_THRESHOLD is set, use it to determine whether to create a response file. QMAKE_LINK_OBJECT_MAX is then ignored. The response file contains objects and libraries. If QMAKE_RESPONSEFILE_THRESHOLD is not set, use QMAKE_LINK_OBJECT_MAX to determine whether to create a response file. The response file contains only object files. QMAKE_LINK_OBJECT_SCRIPT is used in both cases to specify a common base name of all linker response files.
