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.
This patch provides a new option '-vv' for perf which will print the
compiled-in status of libraries.
The 'perf -vv' is mapped to 'perf version --build-options'.
For example:
$ ./perf -vv
perf version 4.13.rc5.g6727c5
dwarf: [ on ] # HAVE_DWARF_SUPPORT
dwarf_getlocations: [ on ] # HAVE_DWARF_GETLOCATIONS_SUPPORT
glibc: [ on ] # HAVE_GLIBC_SUPPORT
gtk2: [ on ] # HAVE_GTK2_SUPPORT
libaudit: [ OFF ] # HAVE_LIBAUDIT_SUPPORT
libbfd: [ on ] # HAVE_LIBBFD_SUPPORT
libelf: [ on ] # HAVE_LIBELF_SUPPORT
libnuma: [ on ] # HAVE_LIBNUMA_SUPPORT
numa_num_possible_cpus: [ on ] # HAVE_LIBNUMA_SUPPORT
libperl: [ on ] # HAVE_LIBPERL_SUPPORT
libpython: [ on ] # HAVE_LIBPYTHON_SUPPORT
libslang: [ on ] # HAVE_SLANG_SUPPORT
libcrypto: [ on ] # HAVE_LIBCRYPTO_SUPPORT
libunwind: [ on ] # HAVE_LIBUNWIND_SUPPORT
libdw-dwarf-unwind: [ on ] # HAVE_DWARF_SUPPORT
zlib: [ on ] # HAVE_ZLIB_SUPPORT
lzma: [ on ] # HAVE_LZMA_SUPPORT
get_cpuid: [ on ] # HAVE_AUXTRACE_SUPPORT
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
v3:
One bug is found in v2. It didn't process the option like '-vabc'
correctly. Fix this bug.
v2:
Use a global variable version_verbose to record the number of 'v'.
