[PATCH] cygport/lib/src_test.cygpart: cygtest check target patch

cygport/lib/src_test.cygpart: cygtest check target patch

make -n does not always reliably detect targets when there are dependency errors
make -in ignores errors and correctly detects when targets are/not available

	$ make -n test &> /dev/null; echo $?
	2
	$ make -n check &> /dev/null; echo $?
	2
	$ make -in test &> /dev/null; echo $?
	2
	$ make -in check &> /dev/null; echo $?
	0
