This sounds awfully wasteful.

The recipe for the install target knows exactly each of these
programs are installed, but yet the above is running around inside
$prefix to find them after the fact.

It also looks incorrect, too.

It is not guaranteed that $prefix does not contain any $IFS
whitespace in it, and worse yet, $prefix may not contain $bindir or
$libexecdir in it, so find may never reach these binaries.

It also depends on "strip" not to break handlinks to the same
binary.  "git" is linked to many built-in command binary like
"git-cat-file" and "git-remote-$curl" for various protocols are
installed by creating links to "git-remote-http".  It seems that the
"strip" command from GNU binutils package strips such a binary
in-place, but I do not think there is no fundamental reason to
believe that everybody else's "strip" would behave that way.

I would have expected that 'install-stripped' and 'install' targets
would run the same recipe, and when $(install_bindir_programs) are
installed in $(bindir) using $(INSTALL), we would optionally pass
the '--strip' option to the $(INSTALL) program when the recipe is
run for the install-stripped target.  All the tricky symlinking,
hardlinking and copying happens only on the result of that step, and
the strip step should happen before that, I would think.
+.PHONY: install-gitweb install-doc install-man install-man-perl install-html install-info install-pdf install-stripped
Split the overly long line like this into two or more.
 .PHONY: quick-install-doc quick-install-man quick-install-html
 install-gitweb:
 	$(MAKE) -C gitweb install

Maybe hardlinks?

Did you mean copying recipe of 'install' to 'install-stripped' and the 
latter s/$(INSTALL)/$(INSTALL -s --strip-program="$(STRIP)"/)?
