Easiest way is typically something like this in the makefile:

docbook_version = $(shell docbook2man --version 2>/dev/null)
ifneq "$docbook_version",""

mymanpage.1:
        ## Real docbook build rules here

else

mymanpage.1:
        if [ -e $@ ]; then \
                echo "No 'docbook' installed, using pregenerated man
pages" >&2 ; \
        else \
                echo "Pregenerated manpages are missing and no docbook
found!" >&2 ; \
                exit 1 ; \
        fi

endif

Such stuff will take an order of magnitude less time than trying to
patch GIT to preserve metadata that most projects don't want
preserved.  You may also find it's easier to just comment out the
documentation build rules if you are always guaranteeing that the docs
have been compiled.
