Delphi currently produces applications that can only run on ARMv7 + NEON processors. There is no way around that limitation.
There is QC report for supporting processors without NEON [Android] Add support for processors without NEON and QC report for supporting Intel based Android devices [Android] [Intel] CPU/Processor compatibility
There have also been some experiments that prove Delphi compiled apps can run on Intel devices via ARM emulation Tomohiro Takahashi on Twitter: "FireMonkey app(for ARMv7) works on Intel-based ASUS ZenFone 4(Atom, Kitkat 4.4.2) "
Native Intel support is on the current Delphi roadmap scheduled for after 2014
Getting correct market shares based on CPUs is almost mission impossible, since Google does not provide CPU based statistics, like it does for Android versions, screen sizes and OpenGL versions: Android statistics
