Comment (by MikolajKonarski):

 Replying to [comment:9 rwbarton]:

 Thank you for your feedback. I've updated the wiki page.

 Re anticipating setting for all possible systems, how would it hurt, if
 i386 GHC, whenever if detected that TARGET /= HOST, always kept setting
 something like
 {{{
 --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc-option="-optl-m32"
 --ld-option="-melf_i386"
 }}}
 It's not x86_64 specific, at least, isn't it? As a default, it's less
 clean but more effective than the optimistic empty list of options.

 Thank you for the {{{lib/settings}}} suggestion. I will try that and
 report here.
