I dont want to see that file because its just a tmpfile.
mkdir $foo
make ARCH=ppc tags &
make ARCH=ppc O=$foo -j menuconfig 
make ARCH=ppc O=$foo -j all

Its just in the way when doing diffs. and make clean may remove the tags
file. But its just silly to expect 'make tags; make clean' to get rid of it.
