    libstdc++: Use LTLIBICONV when linking libstdc++.so [PR93602]

    This fixes missing libiconv symbols when libstdc++ is built on a system
    that has libiconv installed. If the libiconv headers are found then
    libstdc++ depends on libiconv_open etc instead of libc's iconv_open. But
    without this fix libstdc++ is not linked to the libiconv library that
    provides the definitions of those symbols.

    As discussed in PR 93602 this changed means that libstdc++.so.6 might
    have an rpath pointing to the location of the libiconv.so library. If
    that is not desired, then GCC must be configured to link to a static
    libiconv.a instead, using either --with-libiconv-type=3Dstatic or an
    in-tree build of libiconv.
