 Yes, the crti/crtn sources are for the no-opsys embedded
arm/strongarm/xscale-elf targets, not for Linux.  Please
see the 'gcc/config/arm/t-linux' and compare the EXTRA*
stuff with the stuff in those 't-*elf' there.  And you
will see that only 'crtbegin.o' and 'crtend.o' should be
built for Linux/ARM...

 The 'C-startups': 'crt1.o', 'crti.o' and 'crtn.o' belong
to the C-library, meanwhile the 'C++-startups': 'crtbegin.o'
and 'crtend.o' belong to GCC. Sometimes the C-library has
not the 'crti.o' and 'crtn.o', maybe not even the 'crt1.o'.
This is the case with Solaris2, so the 'gcc/config/sparc'
and 'gcc/config/i386' has their sources for Solaris2/Sparc
and Solaris2/x86.  The 'mips*-elf' targets seem also now
have sources for 'crti.o' and 'crtn.o'.
