* Fix error message regression
Passing a non-existent program for --with-hc-pkg used to say this:
$ ./Setup configure --with-hc-pkg=foo
Configuring QuickCheck-2.0...
/bin/sh: foo: command not found
Setup: executing external program failed: "foo" --global list >tmp23634
Now it is rather less useful:
$ ./setup configure --with-hc-pkg=foo
configure: Reading installed packages...
zsh: 23596 exit 127 ./setup configure --with-hc-pkg=foo
This patch restores the old behaviour, slightly improved:
$ ./Setup --with-hc-pkg=foo configure
configure: Reading installed packages...
Setup: executing external program failed (exit 127) : foo --global list
M ./Distribution/Simple/Utils.hs -2 +7
