You better dismiss the idea of using druntime/phobos. They are not optimized for code size and contain a lot of stuff that'll never work. You can replace the core.stdc headers with bindings for nanolib, but again it's not necessary for doing useful stuff and should be done later.
The minimum runtime I have made does fit in 64k rom/ 64k ram, which all STM32F4 devices have. With some work it may even fit to the smaller memory of STM32F0.
I have not yet needed anything from libc/phobos in my programs.
