What toolset configuration are you using?  crti.o should be installed
with
the toolset.  It should be part of the m68k elf toolset.  You might have
a coff
configuration installed.  In the RPMS, they end up:

/opt/rtems/lib/gcc-lib/m68k-rtems/2.95.2/crti.o
/opt/rtems/lib/gcc-lib/m68k-rtems/2.95.2/crtn.o

Magically. :) 

It is a special gcc language to describe various things like linking, 
preprocessing flags, etc.  It gives the end user a high degree of
control
over things that would otherwise require rebuilding the toolset.

>From RTEMS perspective, it lets you do board specific things without
modifying the toolset source.  GCC should not know about the particulars
of the gen68360 BSP.
