Allow for Runtime-less build of GDC and GNAT
Both D and GNAT have their own runtimes (resp. libphotos and libada).
It is still possible to build the compiler proper without any runtime,
and have an external runtime installed later. This is most commonly
found in embedded systems.
An example for D is: https://github.com/KitsunebiGames/tinyd-rt
An example for Ada: https://github.com/Fabien-Chouteau/bare_runtime
