Starts adding a stub X86 configuration which doesn't attempt
the system specific pieces yet. This is mostly to have a point
to add back in the f80 calls so they can be removed from every
other target.

Subject: [PATCH] RuntimeLibcalls: Avoid adding f80 calls to default set
Starts adding a stub X86 configuration which doesn't attempt
the system specific pieces yet. This is mostly to have a point
to add back in the f80 calls so they can be removed from every
other target.
