Force -fPIC when linking against dynamic libraries on Mac OS/X.
Otherwise you get
/tmp/ghc7602_0/ghc7602_0.s:207:0:
   non-relocatable subtraction expression, "___stginit_Lib_dyn" minus "L1x2;4"
/tmp/ghc7602_0/ghc7602_0.s:207:0:
   symbol: "___stginit_Lib_dyn" can't be undefined in a subtraction expression
