Why aren't you using the specific options for profiling?
$ cabal configure --help | grep profiling
 -p --enable-library-profiling     Enable Library profiling
   --disable-library-profiling    Disable Library profiling
   --enable-executable-profiling  Enable Executable profiling
   --disable-executable-profiling Disable Executable profiling
This gives the following error:

$ cabal configure  --enable-executable-profiling
...
$ cabal build
...
    cannot find normal object file `'
    while linking an interpreted expression

However when I apply the same trick as before, first building normally
then building with profiling enabled, it works:

$ cabal configure
...
$ cabal build
...
$ cabal configure  --enable-executable-profiling
...
$ cabal build
...
success!

Thanks for the hint!
