All calls to QINSTALL or QINSTALL_PROGRAM were written into Makefiles
with a preceding dash which lets make ignore the command's exit code.
Scripts (and users) calling 'make install' had no way to determine if an
installation completely succeeded, unless they inspected make's output
or the installation tree.
Remove the leading dash from those commands to stop 'make install' on
failure. Users who really want to ignore the exit codes can run 'make -k
install'.
[ChangeLog][qmake] Installation targets do not ignore the exit code of
QINSTALL and QINSTALL_PROGRAM anymore.
