somewhere in the code these symbols are being referenced, and so at
final link code for them is being pulled in.

my guess is that you are compiling in managers you are not using.  If
you are using hand-built Makefile with RTEMS-provided makefile includes,
I think if you define MANAGERS= (nothing) then you will not get extra
code, or only tiny stubs.
