Use make-check.bin instead of make.bin when running testplanner.pl.

Running testplanner.pl with jom fails with error: "testplan generation
failed". Since we want to use jom for building Qt libraries, changed
testplan generation to use make-check.bin which is always the actual
make i.e. nmake/mingw32-make on Windows.
