Just to make sure I don't misunderstand - you want to build the
contents of ghc/compiler/ in profiled and concurrent form, and not
just the prelude libraries?

That suggests a bug in the concurrent bits, since the last version of
ghc/compiler/hsc linked would have been the concurrent version.
I'm afraid a non-empty setting of GhcCompilerWays doesn't generate
separate hsc binaries for the different ways, instead it silently
overwrites hsc. This is a Makefile bug, which I'll fix. (To do this
yourself, change HS_PROG=hsc to HS_PROG=hsc$(_way) in
ghc/compiler/Makefile.)
Re: bus error, I'll try to reproduce it here.
