higan actually has an own header settings.h that defines an own thread_local
(to __thread or empty).

The attached patch fixes the FTBFS by including that header just like 
the arch-specific implementations do.

These thread_local #define's in libco/settings.h should also be replaced 
with an #include <threads.h>, but that's a separate issue.
