I get the same test suite results with:

powerpc-*-eabi* | powerpc-*-rtems*)
	tmake_file="${tmake_file} rs6000/t-ppccomm rs6000/t-savresfgpr 
rs6000/t-crtstuff t-crtstuff-pic t-fdpbit"
	extra_parts="$extra_parts crtbegin.o crtend.o crtbeginS.o crtendS.o 
crtbeginT.o ecrti.o ecrtn.o ncrti.o ncrtn.o"

I have absolutely no idea what the difference is between

extra_parts="$extra_parts crtbegin.o crtend.o crtbeginS.o crtendS.o crtbeginT.o 
ecrti.o ecrtn.o ncrti.o ncrtn.o"

and

extra_parts="$extra_parts crtbeginS.o crtendS.o crtbeginT.o ecrti.o ecrtn.o 
ncrti.o ncrtn.o"

What is the purpose of the ctrbegin.o and crtend.o?
