dependencies: build a host-tar if no suitable tar can be found Some toolchains, like the one built with buildroot itself, use hardlinks (for example to link between the c++ and g++ binary). Unpacking such a toolchain with the --strip-components options does not work correctly if the system tar is too old (<1.17). Even recent releases of RedHat/CentOS still ship with tar 1.15. This patch checks for a suitable tar version (tar 1.17+) on the host system, and adds host-tar to the host dependencies if none can be found. host-tar is download and extracted as cpio.gz instead of tar.gz, to prevent chicken-egg problem.

Globally replace $(HOST_DIR)/usr/bin with $(HOST_DIR)/bin Since things are no longer installed in $(HOST_DIR)/usr, the callers should also not refer to it. This is a mechanical change with git grep -l '$(HOST_DIR)/usr/bin' \| xargs sed -i 's%$(HOST_DIR)/usr/bin%$(HOST_DIR)/bin%g' Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> 2017-07-05 13:14:19 +02:00			`TAR = $(HOST_DIR)/bin/tar`
package/pkg-generic: handle host-tar as an extract dependency This moves the host-tar dependency handling from DEPENDENCY_HOST_PREREQ to an extract dependency. To achieve that, check-host-tar.mk fills in the BR2_TAR_HOST_DEPENDENCY variable with host-tar if building a host-tar is needed. The name BR2_TAR_HOST_DEPENDENCY has been chosen because it matches the name BR2_CMAKE_HOST_DEPENDENCY already used in check-host-cmake.mk. The BR2_TAR_HOST_DEPENDENCY is added to all packages, except host-tar itself (obviously) and host-skeleton, because we depend on host-skeleton to install host-tar properly in HOST_DIR. In addition, we modify tar.mk to explicitly build host-tar without ccache: since ccache source code is available as a tarball, ccache will obviously depend on host-tar if the system tar is insufficient. Finally, to make things really clean, we also add $(BR2_TAR_HOST_DEPENDENCY) to the dependencies of the tar filesystem format, since it requires tar, so we'd better make sure we have a suitable tar.
