Linker Error on Hello

Anyone know how I can fix this linker error?

Hi,

I fixed the NM variable issue with compiling Hello for SPARC RTEMS.  Now I believe I have a linker issue.

I don't think __DTOR_END__ has ever been declared in a start.S on any version of RTEMS for
any architecture. It is not in the start.S on the 4.10 branch of the community version. I have no
idea who added that to your version.

Do you have enough local history to see what happened?

Any ideas?  Can someone help with this?
