We've had an OOB sync w/ Simon and Ioanna, and it was agreed to let this one be sponsored separately from Simon's usual glibc uploads.
@joalif: your debdiff looks good overall, thanks! Given this is fixing cross-compilation for both i386 and m68k, could you add that second arch into the test plan? I'm going to sponsor this for Noble, as my test plan request is a minor change that should hopefully be trivial to include and test.
