0f9c0bf3d5 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'

e09e1873a1 support/dependencies: ensure we have 'file' on the host
Recently, the autoconf macros for libtool started using '/usr/bin/file'
to determine the type of library that is generated by the toolchain.
Packages that use this recent version of the libtool autoconf macros
will fail in a rather dramatic way when /usr/bin/file is not present
on the host: the package will still build but no shared library is
generated, which in turn may cause build failures in other packages
that link with it.

For example, libpng's configure determines that it is not possible to
build a shared library on MIPS64 because the expected output from 'file'
is not present. Therefore, only a static libpng.a is built. Later,
bandwithd links with -lpng but it doesn't use the pkg-config's
Private-Libs (because it's not linking statically) and it doesn't have
access to the NEEDED reference from the shared library. Therefore, it
doesn't link with zlib and fails with

    pngrutil.c:(.text+0x55c): undefined reference to `inflate'

We cant use host-file because it is itself an autotools package and is
itself using libtool, so this would be a chicken-n-egg problem. Besides,
the libtool script really wants to call /usr/bin/file, so it would not
even find our host-file anyway.

So, just require that '/usr/bin/file' is present on the host.

40685f6a51 support/dependencies: use the new kconfig option to check UTF8 locale
Currently, we require a host with an UTF-8 locale as soone as we build a
Buildroot toolchain with support for locales. This means that we do
erquire such a locale when building a toolchain with either uClibc,
glibc or musl.

However, glibc and musl do not require such a locale to be present.

Use the new option to check if an UTF8 locale is needed on the host,
rather than deriving that from toolchain settings.

c2d80a8c5d core: don't build host-cmake if it is available on the build host
Currently all cmake packages depend on host-cmake. Unfortunately
host-cmake takes a long time to configure and build: almost 7 minutes
on a dual-core i5 with SSD. The time does not change even with ccache
enabled.

Indeed, building host-cmake is avoidable if it is already installed on
the build host: CMake is supposed to be quite portable, and the only
patch in Buildroot for the CMake package seems to only affect
target-cmake.

Thus we automatically skip building host-cmake and use the one on the
system if:
 - cmake is available on the system and
 - it is recent enough.

First, we leverage the existing infrastructure in
support/dependencies/dependencies.mk to find out whether there's a
suitable cmake executable on the system. Its path can be passed in the
BR2_CMAKE environment variable, otherwise it defaults to "cmake". If
it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY
to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and
override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using
our own cmake (the old behaviour).

Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake
to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE)
instead of $(HOST_DIR)/usr/bin/cmake.

Unlike what we do for host-tar and host-xzcat, for host-cmake we do
not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake
would be a dependency for _any_ package when it's not installed on the
host, even when no cmake package is selected.

Cmake versions older than 3.0 are affected by the bug described and
fixed in Buildroot in ef2c1970e4 ("cmake: add patch to fix Qt mkspecs
detection"). The bug was fixed in upstream CMake in version 3.0 [0].

Amongst all the cmake packages currently in Buildroot, the currently
highest version mentioned in cmake_minimum_required() is 3.1 (grantlee
and opencv3).

Thus we use 3.1 as the lowest required cmake for now, until a package is
bumped, or a new package added, with a higher required version.

ef7cc99c7a pkg-generic: fix fallout of <pkg>_STRIP_COMPONENTS introduction
The introduction of <pkg>_STRIP_COMPONENTS broke the build of the
target tar package, because support/dependencies/check-host-tar.mk
defines TAR_STRIP_COMPONENTS to --strip-components. Which leads to
have the package infrastructure do:

 $$(TAR_STRIP_COMPONENTS)=$$($(2)_STRIP_COMPONENTS)

which for the tar package evaluates to:

 $$(TAR_STRIP_COMPONENTS)=$$(TAR_STRIP_COMPONENTS)

which evalutes to:

 --strip-components=--strip-components

Which obviously doesn't work really well. And in fact the
TAR_STRIP_COMPONENTS definition in
support/dependencies/check-host-tar.mk is no longer necessary: it was
needed in the days where we were trying to support old tar versions
that did not support --strip-components. But nowadays, when such an
old tar version is encountered, we build our own host-tar which
supports --strip-components.

514d7cab61 infra: do not append an empty LD_LIBRARY_PATH
When we set LD_LIBRARY_PATH when building our host tools, we append any
pre-existing value to our custom path:
        LD_LIBRARY_PATH="$(HOST_DIR)/usr/lib:$(LD_LIBRARY_PATH)"

But then if LD_LIBRARY_PATH was previously empty, we end up with an
LD_LIBRARY_PATH that ends with a colon.

Also, when we check that an existing LD_LIBRARY_PATH does not contain
CWD, we previously did not look for a zero-length prefix.

Since 'man ld.so' says of LD_LIBRARY_PATH:
    A colon-separated list of directories in which to search for ELF
    libraries at execution-time. Similar to the PATH environment
    variable.

And POSIX states about PATH:
    A zero-length prefix is a legacy feature that indicates the current
    working directory.

And bash also recognises a zero-length prefix to search in CWD:
    A zero-length (null) directory name in the value of PATH indicates
    the current directory.

We may thus end up on a system where a zero-length prefix in
LD_LIBRARY_PATH is interpreted as CWD.

Do not append the previous LD_LIBRARY_PATH if it was empty, and check
for a zero-length prefix when checking dependencies.

f268f7131b .mk files: bulk aligment and whitespace cleanup of assignments
The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.

This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.

Alignment of line continuation characters (\) is kept as-is.

The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
    -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'

Brief explanation of this command:
    ^\([A-Z0-9a-z_]\+\)     a regular variable at the beginning of the line
    \([?:+]\?=\)            any assignment character =, :=, ?=, +=
    \([^\\]\+\)             any string not containing a line continuation
    \([^\\ \t]\+\s*\\\)     string, optional whitespace, followed by a
                            line continuation character
    \(\s*\\\)               optional whitespace, followed by a line
                            continuation character

Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.

This expression was tested on following test text: (initial tab not
included)

	FOO     = spaces before
	FOO     =   spaces before and after
	FOO	= tab before
	FOO	  = tab and spaces before
	FOO =	tab after
	FOO =	   tab and spaces after
	FOO =   	spaces and tab after
	FOO =    \
	FOO = bar \
	FOO = bar space    \
	FOO   =		   \
	GENIMAGE_DEPENDENCIES   = host-pkgconf libconfuse
	FOO     += spaces before
	FOO     ?=   spaces before and after
	FOO     :=
	FOO     =
	FOO	=
	FOO	  =
	FOO =
	   $(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
	AT91BOOTSTRAP3_DEFCONFIG = \
	AXEL_DISABLE_I18N=--i18n=0

After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
  expression leaves the number of whitespace between the value and line
  continuation character intact, but the whitespace before that could have
  changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
  actually makes the code more readable.

Finally, the end result was manually reviewed.

7fa43f911b dependencies: Reject gcj in BR2_NEEDS_HOST_JAVA check
Xbmc uses the Groovy java package to generate API code, for details see
http://wiki.xbmc.org/index.php?title=Codegeneration#How_it_works

Groovy itself is broken when used with gcj:
http://jira.codehaus.org/browse/GROOVY-3701

Xbmc recommends to use another java package instead, like openjdk:
http://forum.xbmc.org/showthread.php?tid=199742

Until we come up with a host package to provide a java setup and
in order to make autobuilder happy let´s reject gcj when we check
for a java installation on the host.

Currently Xbmc is the only package using BR2_NEEDS_HOST_JAVA
so changing the behaviour of dependencies.sh has no side effects.

aac3d2b402 infra: Introduce BR2_HOST_NEEDS_JAVA
XBMC needs Java on the host in order to build, because it uses a
code-generator which is built in two phases: In the first phase SWIG is used
to parse C++ header files that define the API.  SWIG outputs an XML file
that contains a complete description of the structure of the API.  In the
second phase, the XML file is ingested by a Groovy (Java) program that then
creates C++ code that forms the bridge to the scripting language (Python).

The second phase is why we need java on the host.

You can learn more at the XBMC's wiki:
http://wiki.xbmc.org/index.php?title=Codegeneration#How_it_works

In order to check that, this patch introduce this mechanism in
dependencies.sh, and it also defines the variable in Config.in

support/dependencies/dependencies.sh uses #!/bin/sh shebang. It is not
guaranteed that /bin/sh provides an 'echo' implementation that
understands the '-e' flag (interpret backslash escape chars). For
example, dash doesn't.

'printf' is more portable (it must interpret backslash escape chars,
according to POSIX), so use that.

NOTE: Before the previous commit, the dependencies.sh script used
/bin/echo instead of the shell built-in. That's probably why this hasn't

0e4bc50210 core: add BR2_HOSTARCH_NEEDS_IA32_COMPILER option
Some bootloaders (such as Grub) need to be built for x86 (i.e IA32)
even if the target architecture is x86-64. However, when the target
architecture is x86-64, the cross-compiler generated by Buildroot is
not able to generate 32 bits code.

To solve this, we will rely on the host compiler being a x86 + x86-64
compiler. Therefore, this commit introduces the
BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency
checking logic to verify that the host compiler is indeed capable of
building x86 32 bits code.

Conversely, when BR2_TARGET_ROOTFS_CPIO_XZ is enabled, then host-xz is a
build dependency, and no manual action is required from the developer.

Because the second approach is nicer, also build host-xz when xzcat is not

70d6037e8a Infrastructure to warn the user about missing 32 bits libraries
Many users trying to use external toolchains on x86-64 machines get a
very confusing message:

  "Can't execute cross-compiler"

They get this message because they forgot to install the 32 bits
compatibility libraries that are needed to run binaries compiled for
x86 on x86-64 machines.

Since this is the case for both external toolchains and certain
binary-only tools like SAM-BA, we add a new Kconfig option
BR2_HOSTARCH_NEEDS_IA32_LIBS, that packages must select if they need
the 32 bits compatibility libraries. When this option is enabled,
dependencies.sh checks that the 32 bits dynamic library loader is
present on the system, and if not, it stops and shows an error.

The path and name of the 32 bits dynamic loader is hardcoded because
it is very unlikely to change, as it would break the ABI for all
binaries.

Also, it is worth noting that the check will be done even if we're
running on a 32 bits machine. This is harmless, as 32 bits machines
necessarily have the 32 bits dynamic loader installed, so the error
will never show up in this case.

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.

1bbf39bd73 dependencies: add function suitable-host-package
Sometimes, buildroot needs a certain host tool to do its job, e.g. tar. In
many cases, we expect this tool to be present on the host system, but this is
not always the case. Or maybe, the version on the host system is not
suitable, and we need a more recent one.

In some of these cases, instead of bailing out, buildroot could build the
package first (but only if the existing system package is not suitable).

To aid in detecting if a host package is suitable or not, this patch adds a
function suitable-host-package. When called with parameter foo, it will
execute check-host-foo.sh. This script should return either the path to the
suitable host package, or the empty string if no suitable package can be found.
The rules to determine whether something is suitable or not is left to
check-host-foo.sh and depends on foo.

An example usage of suitable-host-package is:
DEPENDENCIES_HOST_PREREQ += $(if $(call suitable-host-package,foo),,host-foo)

To avoid cluttering the existing dependencies.mk file, it includes any
check-host-foo.mk file. These files can be used to hold appropriate
dependency-related actions for foo.

a792668b58 dependencies: move from toolchain/ to support/
As suggested by Arnout Vandecappelle, move toolchain/dependencies to
support/dependencies, as it really is not toolchain-specific anymore.
