Assuming gnu toolchain, you can use ld to link object
files together in a form that is definitely harder to break apart.
(incremental linking to incomplete executable, iirc via switch -x).
That should allow you to produce one big object file (of atleast
haskell bits and c bits) that gets simply passed to ghc.

Using strip to remove debug info/symbol tables also helps somewhat.
(strip.exe is not part of ghc distribution, but you can find it in mingw

Using ar to create archives does not help at all - you can extract the
original files using ar itself.
