From: Arnaldo Carvalho de Melo
Date: Sat Feb 01 2020 - 03:03:59 EST


From: Changbin Du <changbin.du@xxxxxxxxx>

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.
