Improve cross-reference targets

Any of these:

  make xrefs
  make tags
  make TAGS

should create "build/cscope.files", containing a list of the
source files used in preparing to run tests (minus any test
sources). If the 'ctags' or 'etags' programs are installed in the
chroot, they'll be run too.

BUG=none
BRANCH=ToT
TEST=manual

make xrefs
cat build/cscope.files
