I am not sure of these sanitizers can be used in RTEMS at all. We don't 
have virtual memory. Firstly, it would be necessary to check for each 
sanitizer if it uses virtual memory. If yes, then is this absolutely 
necessary or just convenient? Also the sanitizers are not available on 
all LLVM architectures. We have to evaluate if the 
architectures-specific adoptions can be used in RTEMS.
