ghci 7.4.1 no longer loading .o files?

[Evan Laforge]

Is there something that changed in 7.4.1 that would cause it to decide
to interpret .hs files instead of loading their .o files?  E.g.:

% ghc -c T.hs
% ghci
GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package filepath-1.3.0.0 ... linking ... done.
Prelude> :l T
[1 of 1] Compiling T                ( T.hs, interpreted )
Ok, modules loaded: T.
*T>

Versus how this works with 7.0.3:

% ghc-7.0.3 -c T.hs
% ghci-7.0.3
GHCi, version 7.0.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Loading package filepath-1.2.0.0 ... linking ... done.
Prelude> :l T
Ok, modules loaded: T.
Prelude T>

It makes a big difference when ghci decides to go interpret 100 files
vs just sucking in the .o files.

This is OS X, 10.6.8.  Anyone else see this?
