 Ticket spawned from #12240.

 Some time just before commit a33b498d5f648a576dac6d219115866f05721196
 about 40 tests started failing with `BuildFlavour` set to `perf-llvm`.

 @simonmar suggested also testing with `DYNAMIC_GHC_PROGRAMS` set to `NO`
 which results on over 700 of the tests failing.

 @simonmar suggests something is broken in the LLVM backend or in the
 linker.
