    libstdc++: Adjust precompiled headers for freestanding
    
    Co-authored-by: Arsen Arsenović <arsen@aarsen.me>
    
    libstdc++-v3/ChangeLog:
    
            * include/precompiled/extc++.h [!_GLIBCXX_HOSTED]: Do not
            include headers that aren't valid for freestanding.
            * include/precompiled/stdc++.h [!_GLIBCXX_HOSTED]: Likewise.
