No, Android and iOS compilers are not supported.
There are a few issues that prevent that at the moment
- I don't have access to those compilers
- There were some dropped Delphi features (like UTF8String) and there are some architectural changes (like ARC) which could make the adaptation non-trivial
- AFAIK the Apple licensing terms forbid use of 3rd party script engines in iOS, you're supposed to use the JavaScript one they provide, and only it.
