Hmm, is this useful? I don’t see a real pattern. We see failures with
both versions of libc, with all four different versions of ghc

I now gave ghc or haskell-transformers back on some of the failing
architectures. If some of them pass through we can hopefully identify
the cause. Maybe different buildd configuration.

Strangely, the armel build of 7.0.2-1 went through, while 7.0.1-1 did
not. Build logs looks very similar.

Help! :-)

Well, it looks like good news! I just compared
libraries/unix/configure.ac between 7.0.1 and 7.0.2 and 7.0.2 does
indeed look like it contains a fix for this issue. The configure
script now uses AC_SEARCH_LIBS to find sem_close and set up the
linking appropriately.

I don't understand why the build went through — thought it'd need my
bootstrapping optl-pthread hacks as the previous version was mislinked
— but it seems like it did. :-)

Try building *and running* something on one of the failing arches. I
suspect it will work now and we can close this bug.
