Enable new warning for fragile/incorrect CPP #if usage · e5b3492f

Erik de Castro Lopo authored 8 years ago

The C code in the RTS now gets built with `-Wundef` and the Haskell code
(stages 1 and 2 only) with `-Wcpp-undef`. We now get warnings whereever
`#if` is used on undefined identifiers.

Test Plan: Validate on Linux and Windows
