I can do a PR, but what is preferred? There is no configure option to disable libunwind, but I suspect ac_cv_lib_unwind_unw_backtrace can be used to disable it. So 2 options: add unconditional libunwind dependency - this is what upstream does in the RPM spec. Or add a libunwind USE flag and use ac_cv_lib_unwind_unw_backtrace to toggle?
Latter please, as libunwind isn't supported on all arches

As net-misc/openvswitch lacks a dependency on sys-libs/libunwind, installing a binpkg created on such host will result in broken binaries. There is no configure option to disable libunwind, and upstream enables the dependency unconditionally in their RPM spec, but as we support architectures that do not support libunwind, this is not an option. Add a USE flag to toggle libunwind via the autoconf macro.
