can't build very simple package with latest cabal-install

[dmwit]

See also #1236. For a quick review, I have the following problem:

This is using a freshly built cabal-install from current TOT.

Managed to reproduce this using the following .cabal file:

name: issue1244
Cabal-version: >= 1.2
version: 1.0
build-type: Simple

Library

Then I get:

$ cabal configure && cabal build

$ ls

Saved package config for issue1244-1.0 written by Cabal-1.17.0 using ghc-7.4

[23Skidoo]

Some things I've discovered:

a) The error is encountered when we invoke ghc-pkg like that:

("/home/gman/bin/ghc-7.4.2/bin/ghc-pkg",["update","-","--global","--user",
"--package-conf=dist/package.conf.inplace","-v2"])

b) In 1.16, cat dist/package.conf.inplace produces

[InstalledPackageInfo {installedPackageId = InstalledPackageId
"issue1244-1.0-inplace", sourcePackageId = PackageIdentifier {pkgName =
PackageName "issue1244", pkgVersion = Version {versionBranch = [1,0],
versionTags = []}}, license = AllRightsReserved, copyright = "", maintainer =
"", author = "", stability = "", homepage = "", pkgUrl = "", synopsis = "",
description = "", category = "", exposed = True, exposedModules = [],
hiddenModules = [], trusted = False, importDirs = [], libraryDirs = [],
hsLibraries = [], extraLibraries = [], extraGHCiLibraries = [], includeDirs =
[], includes = [], depends = [], hugsOptions = [], ccOptions = [], ldOptions =
[], frameworkDirs = [], frameworks = [], haddockInterfaces =
["/home/cabal-test/issue1244/dist/doc/html/issue1244/issue1244.haddock"],
haddockHTMLs = ["/home/cabal-test/issue1244/dist/doc/html/issue1244"]} ]

However, in the TOT version the contents of that file are just [].

Input given to ghc-pkg via stdin is also different.

Looks like this is what was causing the problem. Bug introduced by @igfoo in 8395c5d. package-conf.inplace is updated by ghc-pkg itself, which is why it was empty when I tested with 1.17.
