The elfutils tools can demangle C++ symbols through the standard

There is a BuildRequires: libstdc++-devel in the elfutils.spec.
But it looks like that isn't enough anymore to pull in libstdc++.so
to build against.
It looks like that is provided through a symlink in gcc-c++.
Should the elfutils.spec just BuildRequires: gcc-c++ instead of
libstdc++-devel? Or is this a packaging/requires issue somewhere
else?
Just in case anybody else is wondering what the correct answer is.
Whether libstdc++.so is provided by by gcc-c++ or libstdc++-devel is
architecture dependent. libstdc++-devel is there for multilib reasons.
You should just depend on gcc-c++ if you need to link against
libstdc++.so. Even if you don't use g++ to link against it. gcc-c++
requires libstdc++-devel.
