fix REPL precompile generation for Pkg

[KristofferC]

For some reason, the auto precompile thing in Pkg messes something up so that the REPL commands for Pkg are not executed when generate_precompile.jl is running. I am guessing the REPL commands get put in while the pretty output from Pkg.precompile is running and that somehow makes them not run. Turn it off for now.

Fixes JuliaLang/Pkg.jl#2200

Probably unrelated, but I've noticed that the build order of some of the stdlibs is a bit whacked. We build Pkg before REPL despite the fact that Pkg depends on REPL. Perhaps the only "problem" is misleading information about how long each stdlib contributes to the build process (which is hardly worth worrying about), but I thought it might be worth mentioning in the context of potential order-dependence of precompilation.

There was a time they were ordered, in fact the comment is still there (although now being completely false):
