The important difference is that before this commit, git-add was
hardlinked to a file outside of DESTDIR. Thus, when the build directory
was removed or you tar'ed DESTDIR, git-add was just a regular file and
all the other builtins were hardlinked to it.

Behavior before commit:
$ touch git git-add && mkdir bin libexec && cp git bin &&
ln git-add libexec/ &&                      ###  the relevant line
tar caf git.tar.gz bin libexec && tar tfv git.tar.gz

bin/
bin/git
libexec/
libexec/git-add


Behavior after commit:
$ touch git git-add && mkdir bin libexec && cp git bin &&
ln bin/git libexec/git-add &&               ### the relevant line
tar caf git.tar.gz bin libexec && tar tfv git.tar.gz

bin/
bin/git
libexec/
libexec/git-add link to bin/git
