   | 	NetBSD/sparc build fails as following:
 
 Notice ...
 
   | #    create  libgcc_s/_clzdi2.d
   | CC=/export/stage/tools/bin/sparc--netbsdelf-gcc [...]
 
   | In file included from _clzdi2.S:2:0:
   | /export/stage/hack/src/external/gpl3/gcc.old/dist/libgcc/config/arm/,,,
 
 There is a strange mix of architectures there, sparc and arm ...
 
 My guess is that this is caused by:
 
   | 	run build.sh as following script:
   | 
   | #!/bin/sh
   | date=`/bin/date +%Y%m%d`
   | workdir=`pwd`
 [...]
   | for machine in amd64 i386 evbarm sparc; do
   |   cd ${workdir}/src || exit
   | 
   |   releasedir=/export/stage/release/${date}
   |   destdir=/export/stage/destdir/${machine}
   |   objdir=/export/stage/tmp
 
 Note, no mention of $machine in objdir
 
   |   echo "===> deleting ${destdir}"
   |   rm -rf ${destdir}
   |   mkdir -p ${destdir}
 
 destdir is cleaned, but objdir ?
 
   |   ./build.sh -m ${machine} -x -j4 \
   |     -U \
   |     -O ${objdir} \
 [...]
 
 The ARM build was immediately before the sparc build, I'd guess that
 there's contamination from the objdir from the evbarm build that is
 affecting the sparc build.
 
 You could delete $objdir before each build, or set
 
 	objdir=/export/stage/tmp/${machine}
 
 or use
 	-O ${objdir}/${machine}
 
 My similar script includes ...
 
 	        /bin/sh build.sh "$@" \
                         -m "${ARCH}"                    \
                         -D "${DEST}"                    \
                         -O "${OBJD}/${REL}/${ARCH}"     \
                         -R "${SNAP}"                    \
                         -T "${OBJD}/${REL}/tools"       \
 
 where REL is what release I am building (7.0 current ...) - including
 that in the names allows the objdir to be retained through all kinds of
 different builds, which makes the -u flag more effective...   Note that
 the tooldir can be shared between different arch builds of the same release
 (that's optional though.)
