description:
Remove "--disable-libstdcxx-dual-abi". This option does not do what
it says: Instead of disabling the dual-abi and letting you choose
which one you want, it disables the cxx11 abi and the
"--with-default-libstdcxx-abi=OPTION" becomes a noop. Removing the
old COW compatibility ABI is not easy. For more info see:
