linux-xlnx: perf: Make perf able to build with latest libbfd

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

Backport commit from mainline to make perf be able to build with both old and
new libbfd.  Fixes errors:
