COMPMID-417: Extract common toolchain support file

The support file is needed as Android toolchains are missing some C++11
functions. It further includes functions that have been introduced in
C++14 but which we already need.

Eventually the support file might become unnecessary if the Android
compilers improve and we switch to C++14.
