+Subject: [PATCH 2/2] tools/sepdebugcrcfix.c: fix build with recent binutils
+
+Moderately recent binutils versions install a <bfd.h> header that
+checks if config.h is included. While this makes sense in binutils
+itself, it does not outside. So the binutils developers have added a
+check: if PACKAGE or PACKAGE_VERSION are defined, they assume you're
+re-using bfd.h outside of binutils, and therefore including it without
+including config.h is legit.
+
+So we take the same approch as numerous users of bfd.h: fake a PACKAGE
+definition. See for example tools/perf/util/srcline.c in the Linux
+kernel source tree.
+
+This fixes the following build error:
+
+In file included from tools/sepdebugcrcfix.c:31:0:
+/home/test/autobuild/run/instance-0/output/host/usr/arc-buildroot-linux-uclibc/sysroot/usr/include/bfd.h:35:2: error: #error config.h must be included before this header
+ #error config.h must be included before this header
