libstdc++ надо новый тащить в соляру для новых плюсов.

If build and host are the same, the GCC you are building will also be used to build the target libraries (like libstdc++). If build and host are different, you must have already built and installed a cross compiler that will be used to build the target libraries (if you configured with --target=foo-bar, this compiler will be called foo-bar-gcc).

In the case of target libraries, the machine you're building for is the machine you specified with --target. So, build is the machine you're building on (no change there), host is the machine you're building for (the target libraries are built for the target, so host is the target you specified), and target doesn't apply (because you're not building a compiler, you're building libraries). The configure/make process will adjust these variables as needed. It also sets $with_cross_host to the original --host value in case you need it.
