[PATCH] MALLOC_CHECK: Allow checking to be disabled from config.mak

The malloc checks can be disabled using the TEST_NO_MALLOC_CHECK variable, either from the environment or command line of an 'make test' invocation. In order to allow the malloc checks to be disabled from the 'config.mak' file, we add TEST_NO_MALLOC_CHECK to the environment using an export directive.

Hi Junio,

Now that the malloc checks have been enabled, running the tests has become somewhat noisy with "malloc: using debugging hooks" messages spewing continuously to the terminal. [I usually run the tests like so:

    ramsay$ time $(make test >test-out 2>&1)
    malloc: using debugging hooks
    malloc: using debugging hooks
    ...
    malloc: using debugging hooks

    real    16m11.408s
    user    5m17.412s
    sys     4m54.786s
    ramsay$ 
]
strace tells me that the controlling terminal, /dev/tty, is being
opened directly in order to write these messages. I find this
annoying, so I tried to disable the malloc checks from config.mak ...

Note that I decided not to write the TEST_NO_MALLOC_CHECK setting to the GIT-BUILD-OPTIONS file, since I prefer to enable/disable the malloc checks myself when running the test script directly.

ATB, Ramsay Jones
