If libperl is installed then the perf tool build will build against
it. There appears to be limited interest in the scripting support for
perl so let's make it opt-in and deprecate it.
With this patch applied you need to add LIBPERL=1 to get libperl
support in perf - there is no warning if libperl is missing, but
building will fail if libperl is missing and the build has LIBPERL=1.
The perf version output is changed to:
```
$ perf version --build-options
perf version 6.17.rc3.g8eca69269947
aio: [ on ] # HAVE_AIO_SUPPORT
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
bpf_skeletons: [ on ] # HAVE_BPF_SKEL
debuginfod: [ on ] # HAVE_DEBUGINFOD_SUPPORT
dwarf: [ on ] # HAVE_LIBDW_SUPPORT
dwarf_getlocations: [ on ] # HAVE_LIBDW_SUPPORT
dwarf-unwind: [ on ] # HAVE_DWARF_UNWIND_SUPPORT
auxtrace: [ on ] # HAVE_AUXTRACE_SUPPORT
libbfd: [ OFF ] # HAVE_LIBBFD_SUPPORT ( tip: Deprecated, license incompatibility, use BUILD_NONDISTRO=1 and install binutils-dev[el] )
libbpf-strings: [ on ] # HAVE_LIBBPF_STRINGS_SUPPORT
libcapstone: [ on ] # HAVE_LIBCAPSTONE_SUPPORT
libdw-dwarf-unwind: [ on ] # HAVE_LIBDW_SUPPORT
libelf: [ on ] # HAVE_LIBELF_SUPPORT
libnuma: [ on ] # HAVE_LIBNUMA_SUPPORT
libopencsd: [ OFF ] # HAVE_CSTRACE_SUPPORT
libperl: [ OFF ] # HAVE_LIBPERL_SUPPORT ( tip:
Deprecated, use LIBPERL=1 and install libperl-dev to build with it )
libpfm4: [ on ] # HAVE_LIBPFM
libpython: [ on ] # HAVE_LIBPYTHON_SUPPORT
libslang: [ on ] # HAVE_SLANG_SUPPORT
libtraceevent: [ on ] # HAVE_LIBTRACEEVENT
libunwind: [ OFF ] # HAVE_LIBUNWIND_SUPPORT ( tip:
Deprecated, use LIBUNWIND=1 and install libunwind-dev[el] to build
with it )
lzma: [ on ] # HAVE_LZMA_SUPPORT
numa_num_possible_cpus: [ on ] # HAVE_LIBNUMA_SUPPORT
zlib: [ on ] # HAVE_ZLIB_SUPPORT
zstd: [ on ] # HAVE_ZSTD_SUPPORT
```
i.e. there is a tip saying about deprecation and how to get support
back.
