Drop dependence on `touch`
This drops GHC's dependence on the `touch` program, instead implementing
it within GHC. This eliminates an external dependency and means that we
have one fewer program to keep track of in the `configure` script

-This means that make thinks that things are out of date when it

-
-The touchy program, like most other programs, creates files with both

-consistent, so doesn't break make.
