Enable bitcode compilation (#11198)

Browse Source 
In order to enable bitcode compilation it is necessary more than adding `-fembed-bitcode`. The `MACOSX_DEPLOYMENT_TARGET` variable must be defined and exported as well.

In this commit the variable is defined grabbing the version of the underlying running macOS.
