 This ticket is to continue work on comment 19 to ticket #5743.

 The issue is only relevant if you wish to use a system provided libffi
 rather than the in-tree libffi.

 PHO's comment[http://hackage.haskell.org/trac/ghc/ticket/5743#comment:19]:
 > ... If I understand this correctly, rts/libs.depend contains only -l
 flags so -L$(FFILibDir) won't be passed to the linker.

 >Apart from that, $(rts_LD_OPTS) seems to be ignored too.
