 Except for `HADDOCK_DOCS` those are all settings for the old build system
 and won't have any effect.  Also `HADDOCK_DOCS` defaults to `YES` anyway,
 so you're effectively compiling with an empty `build.mk` :-)

 I think I see why you don't have the threaded RTS:

 {{{
 GhcRTSWays += $(if $(findstring NO, $(GhcUnregisterised)),thr thr_debug
 thr_l,)
 }}}

 this is different in the 7.4 branch: I made the threaded RTS unconditional
 after 7.4.

 Sparc is unregisterised now that the registerised C backend has been
 removed, which is why you're not getting the threaded RTS.  You can enable
 the threaded RTS explicitly by adding `GhcRTSWays += thr` to your
 `mk/build.mk`.
