ghc doesn't pass flags to ld via -optl

I'm compiling i386 binaries on amd64 linux --- already overcame #9421 (closed), but still not there. When I do the following (using a i386 GHC 7.8.3 on a 64 bit Ubuntu)

~/r/LambdaHack$ cabal install haskell-lexer-1.0 -j1 --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc-option="-optl-m32" --ghc-option="-optl-arch\ i386" --ghc-option="-optl-m\ elf_i386" --ghc-option="-optl-Wl,-m32"  -v3 >& log

I get the attached log with, in particular, these lines:

("/home/mikolaj/local/bin/ghc",["-c","/tmp/4707.c","-o","/tmp/4707.o","-optc-m32","-opta-m32","-optl-m32","-optl-arch\\ i386","-optl-m\\ elf_i386","-optl-Wl,-m32"])
("/usr/bin/ld",["-x","-r","/tmp/4707.o","-o","/tmp/4708.o"])

I panicked, there is probably no bug. The offending call to /usr/bin/ld is done directly by cabal, not by ghc, and so I needed to pass --ld-option as well:

cabal install haskell-lexer-1.0 -j1 --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc-option="-optl-m32" --ld-option="-melf_i386"

This works and so compiling i386 binaries on amd64 Linux finally works for me.

BTW, for completeness, I also had to do

sudo apt-get install libgmp-dev:i386

which unfortunately breaks compilation of amd64 binaries, or hack around as follows

sudo ln -s /usr/lib/i386-linux-gnu/libgmp.so.10.0.2 /usr/lib/i386-linux-gnu/libgmp.so
