Reconfigure required for head.

[Phyx]

Hi all,

I have just committed 4de585a which lifts the MAX_PATH restrictions for
Haskell programs
compiled with GHC 8.6 for Windows users.

However when you update, you *MUST* run configure again. This counts for
ALL platforms otherwise your build will suffer a not so friendly failure.

If you're using Hadrian to build, you must manually update the submodule to
HEAD of master
as the Hadrian submodule hasn't been bumped yet.

Thanks,
Tamar
