#7394: SafeHaskell permits OPTIONS_GHC pragmas

------------------------------+---------------------------------------------
This can be used to launch arbitrary processes at compile-time, and
possibly other dangerous things as well. For example, I'm curious if it
would be possible to override trust with {{{OPTIONS_GHC -trust foo}}}...
Test case, using the hsx preprocessor for XML literals:
{{{
{-# LANGUAGE Safe #-}
{-# OPTIONS_GHC -F -pgmF trhsx #-}
img = <img/>
}}}
The resulting error suggest that the trhsx program was in deed launched:
{{{
pp.hs:3:8: Not in scope: `genEElement'
}}}
