- Apply "reproducible-builds.patch", which makes GHC output
deterministic by disabling multi-threaded compilation. Adding
%define %ghc_smp_mflags %{?_smp_mflags}
to an OBS project configuration re-enables multi-threaded builds,
which might be useful for development projects that don't deliver
binaries.

Subject: [PATCH] Compile with only 1 thread
but give an option to do fast non-deterministic builds
parallel compile causes assignment of random symbol names
so we build single-threaded, which is slower, but gives reproducible results
