libmingw32.a: Not x86_64 PEi386

After a fresh installation of the Haskell Platform (on Windows), I received the following error:

>ghci
GHCi, version 8.0.2: http://www.haskell.org/ghc/  :? for help
ghc.exe: D:/MinGW/bin/../lib/libmingw32.a: Not x86_64 PEi386
ghc.exe: internal error: loadArchive: error whilst reading `D:/MinGW/bin/../lib/libmingw32.a'
    (GHC version 8.0.2 for x86_64_unknown_mingw32)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Invoking GHC will instead error with a bunch of GCC error messages related to standard C library headers (multiple definitions of time_t, etc.).
