typo in decl. of timezone in Time.hsc?

[Antony Courtney]

I think there may be a typo in libraries/base/System/Time.hsc.

Right now lines 362-364 of Time.hsc are:

#if !defined(mingw32_TARGET_OS)
foreign import ccall unsafe "timezone" timezone :: Ptr CLong
#endif

I think the foreign import of "timezone" on line 363 is missing an 
ampersand.  That is, I believe this should be:

#if !defined(mingw32_TARGET_OS)
foreign import ccall unsafe "&timezone" timezone :: Ptr CLong
#endif

This would make it consistent with the declaration on line 355, and 
would allow it to compile in my environment (building ghc as a 
cross-compiler for a target OS in which line 363 of Time.hsc gets compiled).
