make get error from bfd.h

[louisom]

I'm on archlinux with gcc, g++ 6.1.1 when I use make , I got those response

[ 50%] Building CXX object CMakeFiles/quickstack.dir/quickstack.cc.o
In file included from /home/kernel/quickstack/quickstack.h:4:0,
                 from /home/kernel/quickstack/quickstack.cc:1:

  ^~~~~
CMakeFiles/quickstack.dir/build.make:62: recipe for target 'CMakeFiles/quickstack.dir/quickstack.cc.o' failed

after some searching, I put

#define PACKAGE 1
#define PACKAGE_VERSION 1

to avoid this problem.

Maybe we should try to avoid this problem without this kind of dirty trick.

Thanks.
