commit c6090dcebd1fc2a39a95b6fd420e072a2039a81b

    aarch64: align address for BTI protection [BZ #26988]

    Handle unaligned executable load segments (the bfd linker is not
    expected to produce such binaries, but other linkers may).

    Computing the mapping bounds follows _dl_map_object_from_fd more
    closely now.

    Fixes bug 26988.

    (cherry picked from commit 8b8f616e6a594b91d0afb152384bf2a9f72b7288)
