    linux PMDA: provide GNUmakefile hook to change gcc optimization
    
    Conditionally include GNUlocaldefs but do not add GNUlocaldefs
    to the source tree.
    
    So when needed we can create GNUlocaldefs with, e.g.
        CFLAGS_OPT = -O0 -g
    to over-ride the setting from the common builddefs.
    
    Needed on
        vm04        3.10.8   i586    CentOS 5.11 (Final)
    where gcc apparently generates bad code for proc_net_softnet.c with
    -O1 or -O2 and the PMDA suffers a fatal run time "buffer overflow
    detected" error from libc.  When compiled -O0 there is no error and
    valgrind reports no errors from traversing the code in question.

    qa/src/.gitignore: add statvfs

    qa/845: don't run if an acceptable python version not installed
    
    This test uses src/fsstats.python which won't work with older
    versions if Python ... leverage the "at least Python 2.6"
    requirement from the build.
