Here's part of my code:

all-local: ref

ref: ref-html
ref-html: ref-full-html ref-api-html
ref-full: ref-full-html
ref-api: ref-api-html
ref-full-html: $(reference_full_devhelp_chosen) \
ref-api-html: $(reference_api_devhelp_chosen) \

How does make determine whether it should rebuilt? After unpacking, the tag
file obviously has new last-modified/created time - maybe this causes make to
decide it must rebuild? The file is fresh new from the tarball, but it was of
course built at dist-time...
