[PATCH] stdlib/tst-qsort2.c: Fix off-by-one argc interpretation error

[Maciej W. Rozycki]

Hi,

 This fixes an off-by-one argc interpretation error (argv[0] is included 
in the count) in stdlib/tst-qsort2.c causing a segfault if the program is 
called with one command-line argument only (argv[2] is NULL in that case).  

 The issue doesn't trigger in regular testing as the test case is invoked 
without arguments in the test suite, but that doesn't mean the bug is good 
to have.  OK to apply?

	error.
