[PATCH] libstdc++-v3: Have aligned_alloc() on Newlib

[Sebastian Huber]

While building for Newlib, some configure checks must be hard coded.
The aligned_alloc() is supported since 2015 in Newlib.

libstdc++-v3

        PR target/85904
        * configure.ac): Define HAVE_ALIGNED_ALLOC if building for
        Newlib.
        * configure: Regnerate.
