aef5a87ef5 toolchain: disable internal for blackfin
The internal toolchain was a "best effort" approach - we strived to make
it build properly and all but it's mostly untested.
Since it's got issues disable it until it's properly fixed and tested
and leave the official ADI toolchain instead.

2b93fe5374 toolchain-external: add Synopsys DesignWare tools for ARC cores
With this change we add pre-built external toolachins for DesignWare ARC
cores. All currently existed flavours are supported:
 * ARC 700 and ARC HS cores
 * Little- and big-endian configurations

These pre-built tools are built with build scripts available here
(https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/tree/arc-2014.12)
and correspond to arc-2014.12 release of sources.

23ecfd04e6 toolchain-external: fix support for non-ADI Blackfin external toolchains
The computation of TOOLCHAIN_EXTERNAL_BIN has a special case for
Blackfin, where it's set to
$(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/$(TOOLCHAIN_EXTERNAL_PREFIX)/bin
instead of $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/bin for other
architectures.

However, this is actually only true for Analog Devices pre-built
toolchains. Other Blackfin external toolchains (such as ones built by
Buildroot) do not have this special organization.

Therefore, in order to make those non-ADI Blackfin toolchains work, we
need to change the condition from BR2_bfin to testing specifically for
the ADI toolchains.

814f63ec32 toolchain: add link-time-optimization support
Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with
LTO support.

Individual packages still have to enable LTO explicitly by passing '-flto' to
GCC, which passes it on to the linker. This option does not add that flag
globally. Some packages detect if the compiler supports LTO and enable the flag
if it does.

To support LTO, ar and ranlib must be called with an argument which triggers the
usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead
provides wrappers for ar and ranlib that pass the LTO arguments. This way
existing Makefiles don't need to be changed for LTO support. However, these
wrappers are called <tuple>-gcc-ar which matches the pattern to link to the
buildroot wrapper in the external toolchain logic. So the external toolchain
logic is updated to provide the correct symlink.

[Thomas:
  - Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO
    support in binutils. This is a blind option, selected by
    BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke
    directly into gcc Config.in options.
  - Remove the check on the AVR32 special gcc version, which we don't
    support anymore.
  - Adapt the help text of the LTO Config.in option to no longer
    mention "Since version 4.5", since we only support gcc >= 4.5 in
    Buildroot anyway.
  - Fix typo in toolchain-external.mk comment.]

665e13c85e Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS
Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.

As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.

This also helps preparing the addition of other options to select
shared, shared+static or just static.

Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

5aa205eba4 toolchain-external: instrument wrapper to warn about unsafe paths
The CodeSourcery toolchains have a very interesting feature: they warn
the user when an unsafe header or library path is used, i.e a path
that will lead host headers or libraries to leak into the build.

This commit adds a similar functionality into our external toolchain
wrapper, so that it can be used with all external toolchains, and can
also be tuned as needed. By default, the external toolchain wrapper
now gives warnings such as:

  arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-I /usr/foo'
  arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-L /usr/bleh'

but the compilation continues successfully. One can then easily grep
in his build log to search for occurences of this message.

Optionally, if BR_COMPILER_PARANOID_UNSAFE_PATH is defined in the
environment to a non empty value, the external wrapper will instead
error out and abort the compilation.

3e0440407a toolchain/external: fix building the wrapper on MIPS
Some crazy folks use MIPS machines as build machines. ;-)

On MIPS, the only acceptable hash-style is 'sysv', because the MIPS ABI
defines that the GOT ordering to be the same as the symbols ordering,
while GNU hash requires symbols to be sorted by their hash.

Looking at binutils' code, it seems that only MIPS suffers from that
limitation.

Currently, we force the toolchain wrapper to be linked with both hash
styles, which breaks on MIPS.

So, fix that by singling out MIPS, and use sysv in that case, and both
otherwise.

bd0ffe2206 toolchain: do not allow BR2_GENERATE_LOCALE with musl
Generating locales is possible in two situations:

 - With the internal toolchain backend, when the uClibc library is
   used. With uClibc, locales are generated at build time of the C
   library, so with uClibc it's only possible with the internal
   toolchain backend.

 - With either the internal or external toolchain backend when the
   glibc library is used. With glibc, locales can be generated
   afterwards, using the host-localedef utility.

Until we had the musl C library supported in the internal toolchain
backend, the condition: BR2_TOOLCHAIN_BUILDROOT ||
BR2_TOOLCHAIN_USES_GLIBC was correct to capture the above two
situations. Now that we have musl support in the internal toolchain
backend, then BR2_TOOLCHAIN_BUILDROOT is incorrect, and we should use
BR2_TOOLCHAIN_BUILDROOT_UCLIBC instead.

Basic locale support in musl has appeared in musl 1.1.4, but we are
not yet capable of generating the locale files for musl.

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.

3ca5f0b49c toolchain-external: Add CodeSourcery Nios-II 2014.05
This new toolchain release fixes a number of issues found with the previous
one. In particular, the issues with fallocate64, prlimit64 and the
ill-installed linux headers seem to be fixed now.

Therefore, there's not need to sanitize the headers for this toolchain and some
packages should now build fine (e.g. fio).

1b5f0fc8df arch: add an option to specify if the arch has atomic ops
The fact that atomic operations are available is not really a
specificity of the toolchain, but rather of the architecture.

So, add a new option that architectures that have atomic operations
can select. This in turn selects the current toolchain atomic option,
until all packages have been converted, at which point the old
toolchain option can be removed.

cbffd50561 toolchain: Add config option for atomic intrinsics
GCC has several builtin functions that implement atomic operations. Those
functions are architecture specific and may not be implemented by the
specific toolchain. In case of GCC for ARC those functions rely on
LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't
support those instructions but software tries to use them, then application
will be aborted with Illegal instruction exception. To avoid confusion user
should first specify that their CPU supports atomic extension, which will
allow selection of packages that use builtin atomic functions.

a930d9cef6 toolchain: linker options with a $ sign are not supported
As reported in bug #7172 [0], setting BR2_TARGET_LDFLAGS to a value
containing a $ sign can lead to unexpected results.

This is because it is very hard to know when the $ sign gets evaluated:
  - in the Buildroot-level make
  - in the shell called by the Buildroot-level make
  - in the package's own build-system, either at configure time, in the
    Makefile, in a shell in the Makefile...

So, it is very difficult to know how much escaping that would need.

A proposal is to use a shell variable to pass such values unmolested.
But it is not that simple either, since it still contains a $ sign, and
there is not much certainty as to when it would be evaluated.

Instead, just document this limitation, both in the help text for
BR2_TARGET_LDFLAGS, and in the known-issues section in the manual.

Does not really fix #7172, but at least the limitation is documented.

11c1076db9 toolchain: add option to copy the gconv libraries
The gconv libraries are used to translate between different character sets
('charsets', even 'csets' sometimes). Some packages need them to present
text to the user (eg. XBMC Gotham).

In (e)glibc they are implemented by the internal implemenation of iconv,
called gconv, and are provided as dlopen-able libraries.

Note that some gconv modules need extra libraries (shared by more than
one gconv module), so we must, when adding a subset of modules, scan the
installed modules in search of the missing libraries.

[Thomas: add general explanation in expunge-gconv-modules and fix
coding style.]

1cfeed1a4d toolchain-external: remove experimental Blackfin toolchain
The 2014R1 toolchain is provided in two flavours by Analog Devices:
one based on gcc 4.3.x, which is considered stable, and one based on
gcc 4.5.x, considered experimental. In commit
5a65b8e185 ("toolchain-external: add ADI
Blackfin 2014R1 toolchain, remove 2012R1") both variants were added.

However, after some testing in the autobuilders, and discussion with
the Analog Devices folks, it turns out that the experimental version
of the toolchain is too experimental. It causes numerous build
failures, and the Analog Devices folks clearly say that it's an early
release and that they expect quite a few problems to show up.

Therefore, this commit removes the experimental flavor and keeps only
the stable variant. Note that the removal/renaming of the Config.in
options is not a problem, since those options were added after the
2014.05 release.

Fixes:
