>How-To-Repeat:
        Try building gcc34
>Fix:
        I can work around the problem by commenting out the lines:

CONFIGURE_ARGS+=       --with-libiconv-prefix=${BUILDLINK_PREFIX.iconv}
MAKE_ENV+=             ICONVPREFIX=${BUILDLINK_PREFIX.iconv}

in the pkgsrc Makefile, after doing this a functional compiler is produced.
This is not really a correct solution.  I tried adding libiconv.a into the
.buildlink/lib directory but the build failed with the same error.
