Subject[PATCH v3 0/5] 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.g4c1df1
dwarf: [ on ]
dwarf_getlocations: [ on ]
glibc: [ on ]
gtk2: [ on ]
libaudit: [ OFF ]
libbfd: [ on ]
libelf: [ on ]
libnuma: [ on ]
numa_num_possible_cpus: [ on ]
