    Exclude tst-realloc from tests-mcheck
    
    The realloc (NULL, 0) test in tst-realloc fails with gcc 7.x but
    passes with newer gcc.  This is because a newer gcc transforms the
    realloc call to malloc (0), thus masking the bug in mcheck.
    
    Disable the test with mcheck for now.  The malloc removal patchset
    will fix this and then remove this test from the exclusion list.
