[Buildroot] [PATCH 0 of 5] toolchain-external: support downloading custom toolchains + related misc. fixes

[Thomas De Schampheleire]

This patch series originates from the need to be able to use a custom external (buildroot) toolchain, downloaded from an scp location. Support for scp is not included in this series (it was submitted previously, but needs to be retriggered) but the prerequisites relevant for toolchain-external are.

While I was at it, a few CodeSourcery typos were fixed as well.

For the patches related to host-tar, I would like to get some feedback regarding the best way to handle this. I found an earlier thread (http://lists.busybox.net/pipermail/buildroot/2011-March/042191.html - alsa-utils and nctp troubles with 2011.02) where the tar issue was left to rest because it was attributed to an old distribution. However, RedHat/CentOS still ship these old versions of tar, so I think the problem remains. The proposed changes do work and fix my problems, but may need refinement (as described in the patch comment).

[Buildroot] [PATCH 1 of 5] toolchain-external: allow downloading a custom toolchain

[Thomas De Schampheleire]

Custom external toolchains currently already have to be extracted by the user. This patch adds support for downloading a custom toolchain in the form of a tarball, which will be extracted by buildroot.

[Buildroot] [PATCH 2 of 5] Support URI schemes in DOWNLOAD function, when not using gentargets

[Thomas De Schampheleire]

When using the gentargets/autotools/cmake infrastructure, the DOWNLOAD function uses an appropriate download method based on $(PKG)_SITE_METHOD, which is autodetected based on the URI if none was explicitly set.
When the DOWNLOAD function is called directly, when not using gentargets, the SITE_METHOD is not autodetected, and thus the download defaults to wget.

This patch adds URI scheme detection directly to the DOWNLOAD method, in case no SITE_METHOD was detected yet.

[Buildroot] [PATCH 4 of 5] tar: create a host version

[Thomas De Schampheleire]

Some systems, like RedHat/CentOS, are even today shipped with ancient versions of GNU tar, like 1.15. This can cause trouble, for example when unpacking archives containing hardlinks with the --strip-components option.

To avoid such problems, let buildroot create a host-tar that can be used when unpacking.

[Buildroot] [PATCH 5 of 5] toolchain-external: use host-tar instead of tar to unpack toolchains

[Thomas De Schampheleire]

Using the system tar with --strip-components causes problems when its version is too old (<1.17). Even recent releases of RedHat/CentOS still ship with tar 1.15. To avoid such problems, always use host-tar instead of tar to unpack toolchains.

To be honest, I'm not sure what the best way is to handle this. The same problems with tar could occur in other places than just external toolchains. So maybe we should use host-tar in more places.
On the other hand, most users have a recent, working, tar version on there system. It may thus make more sense to detect the system tar version and only use host-tar if it's too old.

It turns out that this has the annoying side-effect of re-running the
'ext-toolchain-installed' step each time, because host-tar is not an
existing file. One can workaround this as follows:

include package/tar/tar.mk
$(STAMP_DIR)/tar-installed:
$(BUILD_DIR)/host-tar-$(TAR_VERSION)/.stamp_host_installed
	$(Q)touch $@

TOOLCHAIN_EXTERNAL_DEPENDENCIES = $(STAMP_DIR)tar-installed
$(TOOLCHAIN_EXTERNAL_DIR)/.extracted

This is not very beautiful because you need to include
package/tar/tar.mk to get to $(TAR_VERSION). Is there a better way?

Thanks,
Thomas
