I don't know how this might relate to
<https://sourceware.org/bugzilla/show_bug.cgi?id=15119> (see
<https://sourceware.org/ml/libc-ports/2013-01/msg00084.html> and
<https://sourceware.org/ml/libc-ports/2013-02/msg00021.html> and the rest
of that thread). But my preference for how to address this is definitely
to move to unifying lowlevellock.[ch] files across as many architectures
as possible - which requires someone to understand the differences and
produce a careful analysis that shows what the best form for generic files
is and what cases actually require architecture-specific files to override
those generic files (preferably overriding only the bits that need
overriding).
