Makefile: keep "git" when bindir is execdir

gitster · gitster · commit 6edd14968bf9 · 2009-07-10T20:17:33.000-07:00
For some reason there still are people who use the old style layout
to put everything in $(bindir).  The previous commit breaks the install
for them, because it tries to unconditionally remove git from execdir
and cp/ln from bindir --- oops.
