Hmm, are you using Raspbian? I.e. hard-float abi caught my eye in case of

I'm afraid LLVM is not well guided in your case so could you be so kind and
test if adding -optlc=-mattr=+vfp2 helps? You need to add it to your build.mk
probably and you will need to rebuild everything again...
No change with
SRC_HC_OPTS = -H64m -Rghc-timing -optc-mfloat-abi=hard -optc-march=armv6
-optc-mfpu=vfp -optlc=-mattr=+vfp2
GhcStage1HcOpts = -O -fllvm
GhcStage2HcOpts = -O0 -fllvm
GhcLibHcOpts = -O -fllvm
I still get the error:
===--- building final phase

I don't really understand what is going on here. The file
libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o doesn't even
exist, so when I manually run /usr/bin/ld I get:
$ /usr/bin/ld libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o
/usr/bin/ld: cannot find
libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o: No such file or
directory
What is make really doing here?
My research suggests that this error is a symptom of trying to link
something without the hard-float ABI together with something with a
soft-float ABI. But I don't know where
libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o is coming from.
