sstate.bbclass: make hard links for staging files
Make hard links for staging files instead of copy to save the disk space (3G will be saved for a core-image-sato build), and it doesn't affect much on the build time. The following directories are affected: 1) The sysroot 2) The DEPLOY_DIR 3) The pkgdata [YOCTO #4372] (From OE-Core rev: 5853e0f482b22258c909268fe71673a29e31989b) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
