    libstdc++: Fix freestanding build (PR 92376)

    In a freestanding library we don't install the <pstl/pstl_config.h>
    header, so don't try to include it unless it exists.

    Explicitly declare aligned alloc functions for freestanding, because
    <cstdlib> doesn't declare them.

    Backport from mainline

        * include/bits/c++config: Only do PSTL config when the header is
        present, to fix freestanding.
        * libsupc++/new_opa.cc [!_GLIBCXX_HOSTED]: Declare allocation
        functions if they were detected by configure.
