[PATCH v4 01/11] perf dso: Move libunwind dso_data variables into ifdef

[Ian Rogers]

The variables elf_base_addr, debug_frame_offset, eh_frame_hdr_addr and
eh_frame_hdr_offset are only accessed in unwind-libunwind-local.c
which is conditionally built on having libunwind support. Make the
variables conditional on libunwind support too.
