Comment (by rwbarton):

 My Android cross-compiler (built with my fork https://github.com/rwbarton
 /ghc-android) produces the correct output `0.0\n1.0\n...100.0\n`. Can
 someone who sees the wrong output attach the object files
 `rts/dist/build/PrimOps.o`, `rts/dist/build/StgPrimFloat.o` to this
 ticket? (Or their disassemblies—particularly if they are not ELF object
 files.)
