This patch checks the values passed by CFLAGS (-DHAVE_XXX) and then
print the status of libraries.
For example, if HAVE_DWARF_SUPPORT is defined, that means the library
"dwarf" is compiled-in. The patch will print the status "on" for this
library otherwise it print the status "OFF".
A new option '--build-options' created for 'perf version' supports the
printing of library status.
For example:
$ ./perf version --build-options
or
./perf --version --build-options
or
./perf -v --build-options
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
v4:
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
v3:
Remove following unnecessary help message.
1. [ on ]: library is compiled-in
[ OFF ]: library is disabled in make configuration
OR library is not installed in build environment
2. Create '--build-options' option.
3. Use standard option parsing API 'parse_options'.
v2:
1. Use IS_BUILTIN macro to replace #ifdef/#endif block.
2. Print color for on/OFF.
