8The makefile created in this test contains two hardcoded rules
9for foo.o and bar.o.  It then gives another multiple target rule
10with the same names as above but adding more dependencies.
11Additionally, another variable extradeps is listed as a
12dependency but is defined to be null.  It can however be defined
13on the make command line as extradeps=extra.h which adds yet
14another dependency to the targets.";
