unwanted IMFS and POSIX stuff in executable

[Jerry Needell]

I am building an application that uses the RTEMS CLASSIC API and  only 
the clock manager. The executable contains a lot of code that I don't 
think I am using. I have extracted some examples from the nm output  
file.  I am not using IMFS or POSIX unless they are required by some 
internal RTEMS functions. Is there a way to keep these from being 
compiled into the program? I am trying to find the minimum footprint for 
my application.
