Duplicate removal was added to extract-libs in order to avoid including
the same library multiple times into the linking command line; this could
potentially happen when using "foo.mo-libs" (which adds the library to
all components, causing it to appear N times if the module is composed
of N objects). However, sorting and removing duplicates causes problems
with static linking, and also with space-separated linker options as
found in some Mac OS X packaging systems. Furthermore, the "optimization"
is really a non-problem since we do not expect .mo modules to be composed
of many files.

Peter, can you please apply this directly as it fixes the
build and there are no other pending patches?
