Joerg Bornemann 1d3b190425 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.
