If you build without --profile and then with stack doesn't recompile the second time to create a binary with profiling options if no files have changed. This is in opposition to ghc behaviour. If you build without -prof and then with, ghc will recompile the second time even if no files changed.

Steps to reproduce

For example:

1. Run command stack clean && stack build.
2. Run command stack build --profile.

Expected

Stack builds two times, first without profiling options and then another time with.

Actual

Stack builds only once without profiling. It ignores the second build instruction because no files changed.

Stack version

$ stack --version
Version 1.3.2 x86_64
