well, I don’t know how broken it is, but it is disabled on a lot of
architectures:

# Whether to include GHCi in the compiler.  Depends on whether the RTS linker
# has support for this OS/ARCH combination.

OsSupportsGHCi=$(strip $(patsubst $(HostOS_CPP), YES, $(findstring $(HostOS_CPP), mingw32 cygwin32 linux solaris2 freebsd dragonfly netbsd openbsd darwin)))
ArchSupportsGHCi=$(strip $(patsubst $(HostArch_CPP), YES, $(findstring $(HostArch_CPP), i386 x86_64 powerpc sparc sparc64)))

(from mk/config.mk.in).

Maybe ghci on armel is a low-hanging fruit, specially if this arch
selection was made before http://hackage.haskell.org/trac/ghc/ticket/631
was fixed (see last comment there). 


That makes me also wonder if we can adjust the code in mk/config.mk for
kfreebsd-* and submit it upstream, so that we can remove the special
casing in debian/rules:

ifneq (,$(findstring $(DEB_HOST_ARCH), kfreebsd-i386 kfreebsd-amd64))
        echo "GhcWithInterpreter=YES" >> mk/build.mk
endif



Greetings,
Joachim
