Cover letter [PATCH v4 0/6] Support perf -vv

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
