Please use Fedora 23 x86_64; I have also tested OpenSUSE 13.2 x86_64
before, but not guaranteed to work now.  The script "fork-project.sh"
included in my document[1] will actually copy my package meta data
into the new package.  So, you can simply run that script and it will
add Fedora 23 x86_64 automatically.
Thanks to your previous reminder, I've updated the doc ( :  The reason
why it is shown as "unresolvable" is that they depend on their
Buildroot companion(buildroot-[ARCH]), which take some time to build.
When the build finish, the strace-[ARCH] package will then build.

Thanks
