I also ran into this when I tried to do a Windows build today, so I've 
reverted the patch in my local tree.

Karel: will you look into this?

Note that on Windows, nm is part of the mingw tools that we provide in 
ghc-tarballs/, so if that needs upgrading we'll need to commit new 
versions of the tools (for both 32 and 64-bit mingw).
