Add NO_CROSS_DIRECTORY_HARDLINKS support to the Makefile
When the installed programs are tar'ed up and installed on a system where bin/ and libexec/git-core/ live on different file systems, we do not want libexec/git-core/git-* to be hardlinks to bin/git. Noticed by Cedric Staniewski. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
