This is a little confusing unless you've been through it before.  I expect that
portage has recently installed gcc-4.4.3 (or 4.4.4 on ~x86) so you now have (at
least) two versions of gcc on your machine, but you are still using the older
gcc-4.3.4.

The point is that you now have (at least) two versions of libstdc++.so.6 because
each version of gcc installs its own version of libstdc++.

Somehow the xulrunner build is trying to use both versions of libstdc++.so.6
(I don't know why, but it probably involves .la files, as usual) so I suggest
that you switch to the new gcc-4.4.3 (or 4.4.4) like this:

#gcc-config --list-profiles
[1] i686-pc-linux-gnu-4.3.4
[2] i686-pc-linux-gnu-4.4.3 *    <----- (I'm already using the newer version)

#gcc-config 1
  * Switching native-compiler to i686-pc-linux-gnu-4.3.4 ...

#gcc-config 2
  * Switching native-compiler to i686-pc-linux-gnu-4.4.3 ...

After you switch, you probably should run
#fix_libtool_files.sh 4.3.4
