[Buildroot] [PATCH] package/oprofile: Fix build with binutils_2.34

[Evgeniy Didin <Evgeniy.Didin@synopsys.com>]

After updating ARC toolchain to arc-2019.09 version oprofile_1.3.0
builds started to fail. These failures were caused by binutils 
upstream commit fd3619828e94a ("bfd_section_* macros") which was 
added in binutils-arc. This commit removed some macros that were
used in oprofile_1.3.0. 

With this commit we introduce fix for oprofile wich enables builds
with binutils_2.34 and older versions.

Fixes:

+Subject: [PATCH] Macro wrappers to handle the binutils 2.34 api changes
+
+Changes in binutils 2.34 API prevented oprofile from compiling with
+it.  This patch tests for the changes in the binutils API during
+configuration and selects the appropiate wrappers to allow oprofile to
+compile.  This allows oprofile to compile with both older and newer
+versions of binutils.
