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 'perf -vv' and 'perf -version --build-options'
which will print the compiled-in status of libraries.

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

For example:

$ ./perf -vv or ./perf -version --build-options
perf version 4.13.rc5.gcb1183
dwarf: [ on ]
dwarf_getlocations: [ on ]
glibc: [ on ]
gtk2: [ on ]
libaudit: [ OFF ]
libbfd: [ on ]
libelf: [ on ]
libnuma: [ on ]
numa_num_possible_cpus: [ on ]
libperl: [ on ]
libpython: [ on ]
libslang: [ on ]
libcrypto: [ on ]
libunwind: [ on ]
libdw-dwarf-unwind: [ on ]
zlib: [ on ]
lzma: [ on ]
get_cpuid: [ on ]
bpf: [ on ]
[ on ]: library is compiled-in
[ OFF ]: library is disabled in make configuration
OR library is not installed in build environment

perf config: Add some new -DHAVE_XXX to CFLAGS
