Talking with some debian mips people it looks like the mips{,el} problems about GOT handling are not resolved in the sarge time frame. You can work around them by building a glibc-got-static libc6 (see #274738), but nobody wants to put in the resources for this task. The only package currently directly affected by this is libgcj/gcj from gcc-3.4, however some java related package may depend on gij-3.4/gcj-3.4 as well (gcj-3.3/gij-3.3 isn't available on mips{,el}.
For the gcc-3.4 upload I want to propose to move to the current 3.4.3 release from the gcc-3.4 release branch and upload this change together with the new minor version. Matthias
