As mentioned in PR 90770, this is a patch that Debian have been carrying for some time. The additional unoptimized copies of libstdc++ libs that get built during each stage are never going to be used, so don't bother building them. For a profiled bootstrap this means we won't train the compiler on the unoptimized library code with assertions enabled, but that doesn't seem like a big problem, as the same code has already been compiled once for the main libstdc++ library. * acinclude.m4 (GLIBCXX_ENABLE_DEBUG): Only do debug build for final stage of bootstrap. * configure: Regenerate.
