I'm not sure. Most curious is that this has not come up before in any of my other ARM-build attempts (which produced less-than-working code, but suceeded in compiling).
This seems to be a general ARM thing: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka3934.html ... so not sure why I'm getting it and no one else is.
Copy your last ghc-stage1 invocation step, add "-v -keep-tmp-files" and see what it'll execute for you. At least you should see libraries which are going into the link process. Then write C hello world, compile and link it and see what's going inside linking and compare with ghc. I guess some lib will be missing in case of ghc linking phase so you'll need to add it either into mk/build.mk appropriate option (E.g. -optl-l<your lib>) or just hack DynFlags.hs to include this for you.
