It might be useful to see the actual command line. Clang's makefiles
are created by cmake; you can add VERBOSE=1 to the make command to see
the actual commands during build.

You didn't attach a cygcheck output, as recommended in

Is your Cygwin 64-bit? What is the output of 'uname -a'?

Try re-running cmake with CMAKE_BUILD_TYPE=Release
The debug info can get very large for some object files in clang/LLVM.

Or you could try the suggestion I found after googling for  :
assembler can't write file too big

(disclaimer: I didn't try it)

For the love of God and all that is holy, get rid of that monstrosity!
I don't care about what you did in 2011, let alone in 2008.
If I did, I would visit your website or Linkedin page.
