 I have to add the following lines to my local script to get
 the default ${TOOLDIR}:
 
 ---
 # tooldir settings
 _HOST_OSNAME=`uname -s`
 _HOST_OSREL=`uname -r`
 _HOST_ARCH=`uname -p 2> /dev/null || uname -m`
 # XXX see PR toolchain/54100
 if [ "${_HOST_ARCH}"X = "x86_64X" ]; then
 	_HOST_ARCH=`uname -m`
 fi
 TOOLDIRNAME=tooldir.${_HOST_OSNAME}-${_HOST_OSREL}-${_HOST_ARCH}
 ---
 
 I also wonder if we can share TOOLDIR among the same ${MACHINE_ARCH}
 because there are many '.if ${MACHINE} == "foo"' conditionals in
 src/tools/Makefile.
