 Building unregisterised to test code paths that don't get tested in the
 registerised compile mode.

 The segfault:

 {{{
 "inplace/bin/ghc-stage1" -static  -O -H64m -Wall -Iincludes
 -Iincludes/dist \
   -Iincludes/dist-derivedconstants/header -Iincludes/dist-
 ghcconstants/header \
   -Irts -Irts/dist/build -DCOMPILING_RTS -this-unit-id rts -optc-DNOSMP \
   -dcmm-lint -i -irts -irts/dist/build -irts/dist/build/autogen \
   -Irts/dist/build -Irts/dist/build/autogen -O2 -Wnoncanonical-monad-
 instances \
   -c rts/StgStartup.cmm -o rts/dist/build/StgStartup.o
 }}}

 seems to occur on powerpc, but not on x86_64 or armhf.
