    libstdc++-v3: Update VTV vars for libtool link commands [PR99172]

    This fixes PR 99172

    Currently when GCC is configured with --enable-vtable-verify, the
    libstdc++-v3 Makefiles add "-fvtable-verify=std
    -Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
    commands. The "-fvtable-verify=std" piece causes alternate versions of
    libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
    libtool just removes that piece).

    This patch updates the libstdc++-v3 Makefiles to not pass
    "-fvtable-verify=std" to the libtool link commands.
