dtc files in gnu/usr.bin

Hi,

at the end of a universe run I have the following files in my src tree 
which don’t belong there:

?       gnu/usr.bin/dtc/.depend
?       gnu/usr.bin/dtc/dtc
?       gnu/usr.bin/dtc/dtc-lexer.lex.c
?       gnu/usr.bin/dtc/dtc-parser.tab.c
?       gnu/usr.bin/dtc/dtc-parser.tab.h
?       gnu/usr.bin/dtc/dtc.debug
?       gnu/usr.bin/dtc/dtc.full
?       gnu/usr.bin/dtc/ld.core
?       gnu/usr.bin/dtc/version_gen.h


I especially like the ld.core ;-)

% file gnu/usr.bin/dtc/ld.core
gnu/usr.bin/dtc/ld.core: ELF 64-bit LSB core file x86-64, version 1 
(FreeBSD), FreeBSD-style, from 
'sers/bz/obj/mips.mips64hf/tank/users/bz/head.svn/tmp/usr/bin/ld 
--sysroot'


Can someone please go and see that these files are properly generated in 
the obj directory?
