"git clone --reference" stores just a reference and does not copy the
history.
It's not going to help in the long run because history accumulating on
the HEAD will be duplicated in your release branches. This is not a
problem if you never merge stuff into them, but I don't know how much
(recent) history browsing you want to do from your release checkouts.

Correct. Merging doesn't work if you pick individual patches. This
is a difficult problem, and few VCS seem to have tackled it.
Working with a single tree and ccache would be another alternative
(ccache still runs the preprocessor and hashes its output, so it
doesn't care about file modification times).
