    Subject[PATCH v4 0/6] Support perf -vv
    Date
    We keep having bug reports that when users build perf on their own,
    but they don't install some needed libraries such as libelf,
    libbfd/libibery.

    The perf can build, but it is missing important functionality. And
    users may complain that perf has issue or bug.

    This patch-set support to print the status of compiled-in libraries.

    Once users think perf missing some functionality, it should be very
    easy for them to check the libraries status.

    For example:

    $ ./perf version --build-options
    or
    ./perf --version --build-options
    or
    ./perf -v --build-options
    or
    ./perf -vv

    perf version 4.13.rc5.g6727c5

    1. Also print the macro name. That would make it easier
    to grep around in the source looking for where code
    related a particular features is located.

    2. Update since HAVE_DWARF_GETLOCATIONS is renamed to
    HAVE_DWARF_GETLOCATIONS_SUPPORT
