Both had the same open coded functions, share them so that we can add
tips for opt-in features such as libunwind, coresight, etc.
Examples of use:
$ perf check feature libcapstone
libcapstone: [ on ] # HAVE_LIBCAPSTONE_SUPPORT
$ perf check feature libunwind
libunwind: [ OFF ] # HAVE_LIBUNWIND_SUPPORT
$ perf version --build-options
perf version 6.15.rc1.g113e3df8ccc5
aio: [ on ] # HAVE_AIO_SUPPORT
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
bpf_skeletons: [ on ] # HAVE_BPF_SKEL
debuginfod: [ OFF ] # 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
libcapstone: [ on ] # HAVE_LIBCAPSTONE_SUPPORT
libcrypto: [ on ] # HAVE_LIBCRYPTO_SUPPORT
libdw-dwarf-unwind: [ on ] # HAVE_LIBDW_SUPPORT
libelf: [ on ] # HAVE_LIBELF_SUPPORT
libnuma: [ on ] # HAVE_LIBNUMA_SUPPORT
