Enable Opt_PIC for the dyn way regardless of OSes
From: Kazu Yamamoto
When I build GHC head on FreeBSD, I got the following error. Is newSpark
missing on FreeBSD?

Call hs_init_ghc() from your main() function to set these options.

The same error occurs on NetBSD/amd64. PrimopWrappers.dyn_o has a
direct reference to newSpark but since it resides in the rts, not
ghc-prim, such references must be redirected through PLT. The problem
is that every *.dyn_o, not only PrimopWrappers.dyn_o, is compiled
without -fPIC for OSes other than Windows, Darwin and Linux.
I have no idea why -fPIC isn't enabled for all OSes in the first
place, but the attached patch works at least for me.

Thanks. This patch also solves the problem in my environment.
Would you create a ticket and attach your patch? > PHO
