INIT: uARM no rtos: Align pre-main initialization steps between TCs 

In uARM, the library's hook _platform_post_stackheap_init does not seem to
exist and I couldnot find a documentation describing the initialisation
flow. All we know is that _open is called after RAM init and before the
C++ init, so this is a working placeholder.

This is maybe not acceptable so a uARM lib expert may propose a better
hook to fullfil the requirement.

At least this is a workign setup.

This series should solve issue reported here:
STM32 (At least F401) breaks if Tickers are activated in a global object #2115
