Changing build options rebuild all dependencies

[maxigit]

I'm trying to optimize a program so I do stack build --executalbe-profiling and it take forevers, stack rebuild all the dependencies (which is fine, once). If do the just stack build (because I forgot the --executable-profiling flags) it rebuild again all dependencies . If do again stack build --executable-profiling (because I remember to add the flag), it's rebuilding everything again and that takes forever each time ...

I'm surprised by this behavior because I though stack was keeping every build in cache.
(I'm using stack 1.8).

I believe this is a duplicate of #1132.
