-------------------------------------------------
libbfd has changed the bfd_section_* macros to inline functions bfd_section_<field> since 2019-09-18. See below two commits: o http://www.sourceware.org/ml/gdb-cvs/2019-09/msg00064.html o https://www.sourceware.org/ml/gdb-cvs/2019-09/msg00072.html
This fix make perf able to build with both old and new libbfd.
