That'll be my fault. In the Cabal file the Platform.hs module is only
compiled when the NCG is included, but it's also used by Dynflags.
I'll patch it.

I'm not sure what you mean by "seems to assume that __GNUC__ implies
__thread working."
In rts/sm/GCThread.h, with the line:
extern __thread gc_thread* gct
The __thread attribute is supposed to make the "global" variable gct
into thread-local-storage, so each thread has its own private version
of it. The GCC manual page for it is here: http://gcc.gnu.org/onlinedocs/gcc/Thread_002dLocal.html#Thread_002dLocal
