Unregistered build fails because libghccompat is not built

I believe that this bug:

http://article.gmane.org/gmane.comp.lang.haskell.glasgow.user/9108

Can be fixed by changing the build instructions on this page:

http://www.haskell.org/ghc/docs/6.4.1/html/building/sec-porting-ghc.html#unregisterised-porting

These two lines, currently do *not* cause the .hc files for compat to be created:

$ make boot UseStage1=YES
$ make -k UseStage1=YES EXTRA_HC_OPTS='-O -fvia-C -keep-hc-files'

but changing the first line to:

$ make boot UseStage1=YES EXTRA_HC_OPTS='-O -fvia-C -keep-hc-files'

does.
