Statically allocated build

[Петр Борисенко]

 Hello everyone!
I am currently creating a aerial robot application upon the arm/stm32f4 bsp
(extending it, possibly will contribute soon)
I have just moved from RTEMS5 to RTEMS6 and have a few questions.
1. I don't understand how to build a system fully statically allocated. For
safety reasons I shouldn't use neither heap for the system objects nor
dynamic loading.
2. I have just noticed that `__usrenv.c` has been compiled into my
application. I don't understand how to disable it.


Best regards.
