A bit of both.  The size documentation has not been updated recently.  And
that number doesn't include anything besides RTEMS proper for the version
of RTEMS it was generated against.

It does not include: BSP init/shutdown, malloc and libc initialization 
or any
device drivers, filesystem infrastructure, etc.

It also depends on what you have enabled.  The last sparc-sis build I 
did on the
head has 94,256 bytes in the text segment according to size.
