Not quite. Notice the difference between '-optc-...' and '-optlc-...'

The first one will pass options onto the C compiler (since you use the
GHC executable to compile the RTS and other things, this is
necessary.)

The first one passes the options onto LLVM's code generator tool,
'llc', so it also gets the ABI options right.
