3196096149 package: fix bootloader building
The changes in e055aea216 and
0849e8193e have broken the bootloader
support.

This is because the 'pkgparentdir' macro returns the string 'boot/'
for bootloaders, while the GENTARGETS_INNER macro was testing this
against 'boot' to know if the configuration option to check for this
package is BR2_PACKAGE_* or BR2_TARGET_*.

So, instead of testing against 'boot', we test against 'boot/'.

767ad6900a package: normalize output of 'make external-deps'
For wget-downloaded packages, only the tarball name was displayed,
while for svn/git/bzr packages, the complete repository URL was
shown. As discussed on the list, what we want for 'make external-deps'
is only the tarball name even for git/svn/bzr downloads.

For local packages, we of course keep the full path since it's the
only information that we can provide.

2690e76aa2 Add support for local packages through 'file://' pseudo-protocol
This can be used this way :

<pkg>_VERSION = 42
<pkg>_SITE = file:///some/local/directory
<pkg>_SOURCE = mypkg-$(<pkg>_VERSION).tar.bz2

Can be useful to integrate a home-made project or for testing purposes.
The default command to retrieve files is 'cp' but 'rsync' could also be used.
Through sshfs, it should also be possible to get non-public remote files on a
ssh server.

e055aea216 package: add helper functions to get package name and directory magically
This commit adds the functions "pkgname" and "pkgdir", which can then
be used to automatically find the name of the package and the
directory of the package which does the call to
GENTARGETS/AUTOTARGETS/CMAKETARGETS. These functions use the
$(MAKEFILE_LIST) variable, which make automatically makes available,
and which contains the list of included Makefiles, with the current
Makefile being last. Thanks to this variable and a little bit of
string manipulation, we can easily find out automatically the package
name and the directory it is part of.

These functions are used in later commits to simplify the GENTARGETS,
AUTOTARGETS and CMAKETARGETS calls.

793a2ea517 package: implement a 'local' site method
The new override source directory mechanism allows to tell Buildroot
to use a particular directory as the source directory for a
package. However, this mechanism works with a local override makefile
and not directly within the package recipe itself.

For some use cases, it might be desirable to write a package recipe
which always refers to a local source directory (and not a http, git,
svn or bazaar download). This commit makes this possible by adding the
'local' site method. It allows to write package recipes as follows:

MYPKG_SITE = /tmp/mypkg-source-code
MYPKG_SITE_METHOD = local

[...]

$(eval $(call GENTARGETS,package,mypkg))

4ed4e5016b package: add <pkg>-rebuild and <pkg>-reconfigure
We are often asked "how can I restart the build of a package ?" or
"how can I restart the build of package from the configure part
?". Obviously, tweaking with stamp files is possible, but not very
user friendly.

Therefore this patch adds two new per-package targets: <pkg>-rebuild
and <pkg>-reconfigure. They will remove the right stamp files and
restart the complete build process (by using the 'all' target, so that
not only the package is reconfigured, recompiled and reinstalled, but
the root filesystem images are also regenerated).

da76f0f155 package: enhance infrastructure to support source dir override
When a variable <pkg>_OVERRIDE_SRCDIR is defined, then Buildroot will
no longer try to download, extract and patch the package. It will
simply use the value of this variable as the source directory for the
package. The contents of the package sources will be rsynced to the
package build directory in $(O)/build/pkg-version/.

This can be used to tell Buildroot that the sources for a given
package are inside some directory that you control, and which can be
versioned in Git/SVN, or handled in whichever way you want.

Those <pkg>_OVERRIDE_SRCDIR variables will be defined by a local
makefile included by Buildroot, which will be handled in a later
commit.

a473a616d2 package: change ordering of steps
Currently, the dependency chain is :

 configure -> patch
 patch -> extract
 extract -> depends
 depends -> source + dependencies ready

This is a problem for RTAI, as :

 * In linux/linux-ext-rtai.mk, we need the RTAI source code to be
   extracted/patched by the RTAI package, so we need to have a
   dependency on RTAI.

 * The RTAI package cannot have its configure step executed before the
   Linux kernel is built, because it needs the kernel source code to
   be extracted and configured.

Therefore, we have a sort of circular dependency. We solve this
circular dependency by having the RTAI kernel part depending on
rtai-patch, and having the RTAI userspace part depending on the linux
package. However, for this to work, we have to modify the dependency
chain to:

 configure -> patch + depends
 patch -> extract
 extract -> source
 depends -> dependencies ready

Which means that dependencies are guaranteed to be built not when the
package is extracted, but when the package is configured. Which is
technically more correct that what we were doing in the past.

f940d7602c package: fix <pkg>_DL_VERSION value
993e51bc22 introduced a <pkg>_DL_VERSION
in addition to <pkg>_VERSION. This variable, purely internal to the
package infrastructure, allows to store the *raw* version name, as
defined in the package .mk file. However, as this version string can
contain slashes, it is not appropriate to be part of the build
directory name of the package. This is why <pkg>_VERSION is defined to
be the same thing as <pkg>_DL_VERSION, except that slashes are
replaced by underscores.

However, the initial implementation didn't take into account the case
of host packages. So 763822e874 was
committed to fix this. But unfortunately, this commit got it wrong
again: it forgot the case where <pkg>_VERSION is set, but not
HOST_<pkg>_VERSION. In this case, HOST_<pkg>_DL_VERSION remained
empty. This can be seen for example by building host-sstrip.

This problem has been noticed by Julien Boibessot
<julien.boibessot@free.fr>, who also helped in fixing the
issue. Thanks!

The fix is simply to ensure that <pkg>_DL_VERSION is properly set in
all cases: when HOST_<pkg>_VERSION is defined, when only <pkg>_VERSION
is defined, and when no version is defined.

b0d446dee4 Improve TARGETS handling for bootloaders and kernel
As the kernel and bootloaders do not use the normal BR2_PACKAGE_*
Kconfig options, their target name was not automatically added to the
global TARGETS variable. Each bootloader .mk and the linux.mk had to
add their own target manually to TARGETS, and the package
infrastructure was making tests on non-existing Kconfig variables.

This commit improves the package infrastructure so that it looks at
BR2_PACKAGE_<pkg> for packages, BR2_TARGET_<pkg> for bootloaders and
at the special BR2_LINUX_KERNEL for the linux package.

This allows to simplify a little bit the bootloaders and linux .mk
files.

7a41cbf938 package: fix patching procedure for host packages
The patching procedure was using $($(NOHOSTPKG)_NAME) to find the name
of the package without the host- prefix for host packages, which is
needed to find the package directory and the prefix of the patches.

However, this $($(NOHOSTPKG)_NAME) variable is empty when there is
only an host variant for the package and no target variant for it.

Therefore, instead of using this $($(NOHOSTPKG)_NAME) variable, we now
use a new $(RAWNAME) variable, which is always the name of the package
without the host- prefix, even for host packages.

Thanks to Yann E. Morin for providing the tip on using patsubst
instead of subst.

c4d57780be Makefile.package.in: Makes it possible to override the default extract commands
When using GENTARGETS (or macroes depending on it), there is no way of
specifying a custom extraction procedure. When using the patch one can
simply define $(PACKAGE_NAME)_EXTRACT_CMDS which will override the
default. If non is defined it will fall back to the default extract
procedure.

An example could look like this:

=== PACKAGE BEGIN ===
FGLRX_VERSION=11-3
FGLRX_SOURCE:=ati-driver-installer-$(FGLRX_VERSION)-x86.x86_64.run
FGLRX_SITE:=http://www2.ati.com/drivers/linux/

define FGLRX_EXTRACT_CMDS
	sh $(DL_DIR)/$(FGLRX_SOURCE) --extract $(@D)
endef

$(eval $(call GENTARGETS,package,fglrx))
=== PACKAGE END ===

If the repository is accessed through http(s), you can force the

'svn', respectively and without the quotes.

The package's _VERSION variable defines which commit, revision, tag or
branch should be checked out. For Git, it can be HEAD, a commit ID, a
tag name or branch name (anything that can be checked out with `git
checkout`). For Subversion, it must be a revision number, or HEAD.
