Building gcc-4.4.7 with gcj and gtk USE flags results in a build failure.

I have emul-linux-x86-gtklibs-20121028 installed, but the linker for some reason does not find those libraries.
*** This bug has been marked as a duplicate of bug 444350 ***
I don't understand how this is a duplicate of bug 444350. According to bug 444350: "Just manually emerging app-emulation/emul-linux-x86-gtklibs should help you get gcc building again until someone can add this dependency." As I stated in my initial report, I do have emul-linux-x86-gtklibs installed. It's only gcc-4.4.7 I am having issues with, gcc-4.5.4 and gcc-4.6.3 emerge without errors.
I am sorry for the spam, but gcc-4.4.7 is emerging now. I don't know what changed since yesterday. I suspect it's possible that my rsync mirror wasn't up to date enough to include the necessary fixes until now.
