    support: Fix printf format for TEST_COMPARE_STRING
    
    Fix the following on 32 bits targets:
    
    support_test_compare_string.c: In function ‘support_test_compare_string’:
    support_test_compare_string.c:80:37: error: format ‘%lu’ expects argument of
    type ‘long unsigned int’, but argument 2 has type ‘size_t’ {aka ‘unsigned int’}
    [-Werror=format=]
             printf ("  string length: %lu bytes\n", left_length);
                                       ~~^           ~~~~~~~~~~~
                                       %u
    Checked on arm-linux-gnueabihf.
    
            * support/support_test_compare_string.c
            (support_test_compare_string): Fix printf format.
