First thing to note is that bootstrapping from HC files has bitrotted in 
6.8.x, see http://hackage.haskell.org/trac/ghc/ticket/1346.  I've updated 
the wiki instructions to say this.  You should go back to 6.6.x, or be 
prepared to fix things...  I thought I remembered someone saying recently 
they were looking into getting bootstrapping working again, but I can't 
seem to find it now.

It looks like this comes from mk/bootstrap.mk, which says:

ifeq "$(alpha_TARGET_ARCH)" "1"
PLATFORM_CC_OPTS += -static -w
PLATFORM_HC_BOOT_CC_OPTS += -mieee
endif

So someone in the past thought it was a good idea to pass this option when 
compiling .hc files.  I can't tell you any more than that - perhaps just 
removing that line will get you going again.
