 I have been trying to statically link Pandoc packages to iOS application
 following the guide in
 https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS and it's
 great so far! I have finally successfully use Pandoc library in iOS app,
 but the binary size is very big!

 1. More than 50MB when using Pandoc library.
 2. Around 5MB for simple haskell code.

 I try to add “split-objs: True” in .cabal/config file, but when running
 cabal I got this message:

 {{{
 Preprocessing library pandoc-1.12.2.1...
 unused terminals: 1

 on the commandline: Warning: ignoring -fsplit-objs
 }}}

 And if I ignore that, at the end of build, I get another error message
 that stop the build.

 {{{
 cabal: dist-i386/build/Text/Pandoc_o_split: does not exist
 }}}

 I try with another package and got similar error message. It seems that
 split-objs not only being ignored by cross-compilation ghc, but will also
 fail the build.
