package/oprofile: fix build with binutils >= 2.34
The libbfd library provided by binutils unfortunately changed its API in binutils >= 2.34. This is causing some build failures at the moment on architectures such as ARC that are using a very recent binutils version, but it would also cause build failures on other architectures once they start using binutils 2.34. We fix this build issue by backporting an upstream oprofile patch. However, this patch touches configure.ac, which means we need to autoreconf, which needs another fix in configure.ac for autoreconf to succeed. With all that in place, this commit fixes: http://autobuild.buildroot.net/results/583d281c6cd2aecb65556080b379db24101ae3a8/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

Subject: [PATCH] configure.ac: add foreign option to AM_INIT_AUTOMAKE
|
||||
|
||||
oprofile doesn't provide the NEWS, AUTHORS and ChangeLog file, so
|
||||
autoreconf complains with:
|
||||
|
||||
Makefile.am: error: required file './NEWS' not found
|
||||
Makefile.am: error: required file './AUTHORS' not found
|
||||
Makefile.am: error: required file './ChangeLog' not found
|
||||
|
||||
Such errors can be avoided by passing the "foreign" option to
|
||||
AM_INIT_AUTOMAKE.

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.
