6e3c9ad59e toolchain: merge toolchain-common.in to Config.in
toolchain-common.in is a Config.in file with an uncommon name.
It is just included by toolchain/Config.in, and toolchain/Config.in is
not that long, so instead of renaming the file, merge it to
toolchain/Config.in.

Move the raw contents from the file to the exact location it is
currently included in order to not change the order in the menu.

Update the references in the manual as well.

31a726122f arch: add option to disable internal toolchain backend
Some architectures or specific cores do not have support in upstream
gcc. Currently, they are individually listed as exclusions in the
toolchain choice.

This poses a maintainance burden, as the knowledge about what gcc
version supports what architecture is split across many places: the
toolchain choice, the gcc version choice, the external toolchains.

As a first step, add a blind option that architectures or individual
cores may select to indicate they lack support in our internal backend.

Actual use of the option will come in followup patches.

6eaa6460ba toolchain/buildroot: not available for a few mips cores
Commit 1b974425 (MIPS: add support for M6201 cores) explained that the
new core was not supported by upstream gcc, and as of gcc-8-trunk
that's still the case.

Ditto for 3cfbeb83 (MIPS: add support for P6600 cores).

This means that we currently allow to build an internal tolchain for
those cores, yet we have no suitable gcc version.

Disable the internal backend in this case.

3897ded714 toolchain: Bump ARC tools to arc-2016.09-eng007 and enable PIE
As described at:
4520524ba0
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng007 tag plus a
couple of fixes on top of it that will all make its way in the
next engineering build.

We hope this patch will cure most buildroot ARC failures as it
contains important fixes:

1) PIE fix. We have added PIE support to ARC toolchain at last.
So that should prevent breakage of many packages. As ARC now
supports PIE we remove ARC from BR2_TOOLCHAIN_SUPPORTS_PIE
exclusion in toolchain/Config.in file.

2) Assembler fix. This patch also have changes that fixes frequent
assembler failures, e.g.:
http://autobuild.buildroot.net/results/543/5430b902d900943a34c1888e7e410bd5df367bc2//

We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.

So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

c64f948d2c toolchain: introduce a toolchain knob for NPTL
As our architecture support expands to a number of architectures that
do not implement NPTL threading, and the number of packages that
depend on NPTL specific features, it has become necessary to be able
to know whether the toolchain has NPTL support or not.

This commit adds a new BR2_TOOLCHAIN_HAS_THREADS_NPTL hidden Config.in
option that allows packages to know whether NPTL is available or not.

This hidden option is:

 * Automatically enabled when glibc/eglibc or musl toolchains are
   used, either internal or external.

 * Automatically enabled when an internal uClibc toolchain with NPTL
   support is configured. It is left disabled otherwise for internal
   uClibc toolchains.

 * Configured according to a visible Config.in option for custom
   external uClibc toolchains.

a1d94aaa3a toolchain-external: add support for musl C library
This commit adds support for external toolchains based on the musl C
library, as available from http://www.musl-libc.org.

Note that the pre-built musl toolchains available from
http://musl.codu.org/ are not working for the moment, since they lack
sysroot support. However, this problem has been reported to the
maintainer, who has already added sysroot support in his scripts at
https://bitbucket.org/GregorR/musl-cross, and therefore the next
version of the pre-built toolchains should work with Buildroot
out-of-the-box. In the mean time, the musl-cross script must be used
to build the toolchain.

c5866be0ad toolchain: refactor Stack Smashing Protection support
This commit refactors how Stack Smashing Protection support is handled
in Buildroot:

 *) It turns the BR2_TOOLCHAIN_BUILDROOT_USE_SSP option into an option
    that only enables the SSP support in uClibc, when using the internal
    toolchain backend.

 *) It adds an hidden BR2_TOOLCHAIN_HAS_SSP option that gets enabled
    when the toolchain has SSP support. Here we have the usual dance:
    glibc/eglibc in internal/external backend always select this
    option, in the case of uClibc/internal, it gets selected when
    BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of
    uClibc/external, there is a new configuration option that the user
    must select (or not) depending on whether the toolchain has SSP
    support.

 *) It adds a new options BR2_ENABLE_SSP in the "Build options" menu,
    to enable the usage of SSP support, by adding
    -fstack-protector-all to the CFLAGS.

2babed4a50 toolchain-internal: skip gcc-intermediate when possible
When NPTL support was introduced, gcc required a three stages build
process. Since gcc 4.7, this is no longer necessary, and it is
possible to get back to a two stages build process. This patch takes
advantage of this, by doing a two stages build process when possible.

We introduce a few hidden kconfig options:

 * BR2_GCC_VERSION_NEEDS_THREE_STAGE_BUILD, which is set by the gcc
   Config.in logic to indicate that the compiler might need a three
   stages build. Currently, all versions prior to 4.7.x are selecting
   this kconfig option.

 * BR2_TOOLCHAIN_LIBC_NEEDS_THREE_STAGE_BUILD, which indicates whether
   the C library might need a three stages build. This is the case for
   eglibc, and uClibc when NPTL is enabled.

 * BR2_TOOLCHAIN_NEEDS_THREE_STAGE_BUILD finally is enabled when both
   of the previous options are enabled. It indicates that a three
   stages build is actually needed.

In addition to those options, the uClibc/gcc build logic is changed to
use only a two stages build process when possible.

8d29893893 eglibc: enable support in the Buildroot toolchain backend
Using the newly introduced 'eglibc' package, this commit enables the
option of building a toolchain using the eglibc C library in the
Buildroot toolchain backend.

In details, this commit:

 * Creates a choice to select uClibc or eglibc in the Buildroot
   toolchain backend (in toolchain/toolchain-buildroot/Config.in), and
   removes the fact that the Buildroot toolchain backend forcefully
   enables uClibc (toolchain/Config.in).

 * Creates a BUILDROOT_LIBC variables, which points to the package
   implementing the C library (i.e either 'uclibc' or 'eglibc').

 * Modifies the gcc-final and gcc-intermediate makefiles to use the
   BUILDROOT_LIBC variable instead of hardcoding the use of uclibc.

 * Ensures that TLS support is always enabled when building eglibc.

381616e77a Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC}
Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.

Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

8fda9b7813 toolchain/crostool-NG: mark as deprecated
For the following reasons:
  - it used to be broken without anyone noticing for a long time,
  - it is still not fully integrated within the Buildroot set of options,
  - it has not gained much traction (not even I use it),
  - I've always argued that sustained development should use an external
    toolchain, and not rely on building one with Buildroot,
  - I did not submit any of the enhancements requested during the last
    developpers' day in Brussels,
  - I have neither the incentive nor the time to maintain and enhance it,

it is time to deprecate the crosstool-NG backend for the 2013.05 release.

Then, it will be entirely removed early in the 2013.08 cycle, to let some
time for those that rely on it to voice their opinions. ;-)

moves it from toolchain/gdb to package/gdb.

The target package is now visible in "Package selection for the
target" => "Debugging, profiling and benchmark". The main option,
"gdb", forcefully selects the "gdbserver" sub-option by
default. Another sub-option, "full debugger" allows to install the
complete gdb on the target. When this option is enabled, then
"gdbserver" is no longer forcefully selected. This ensures that at
least gdbserver or the full debugger gets built/installed, so that the
package is not a no-op.

The host debugger is still enabled through a configuration option in
"Toolchain". It is now visible regardless of the toolchain type (it
used to be hidden for External Toolchains). The configuration options
relative to the host debugger are now in package/gdb/Config.in.host,
similar to how we have package/binutils/Config.in.host.

Since gdb is now a proper package, it is no longer allowed to 'select
BR2_PTHREADS_DEBUG' to ensure thread debugging is available when
needed. Instead, it now 'depends on
BR2_TOOLCHAIN_HAS_THREADS_DEBUG'. This option, in turn, is selected by
the different toolchain backends when appropriate. The
'BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED' option is removed, since
we no longer need to know when it is allowed to 'select
BR2_PTHREADS_DEBUG'. Also, the 'BR2_PTHREADS_DEBUG' option is moved to
appear right below the thread implementation selection (in the case of
the Buildroot toolchain backend).

75720db391 xtensa: add support for the Xtensa architecture
The Xtensa architecture had been removed because it required special
handling and depended on additional directories and files that became
obsolete over time. This change is more aligned to other architectures.

[Thomas: rebased on top of the "arch: improve definition of gcc mtune,
mcpu, etc." patch].

d27e09a71a toolchain: make external toolchain the default for AArch64
Our internal toolchain backend does not yet have support for AArch64,
and Crosstool-NG also does not have support for AArch64 at the moment
(though it should be coming quickly since the Linaro AArch64 toolchain
is generated with a modified Crosstool-NG version).

5931db0de9 gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOT
Newer versions of GDB need pthread debugging support if threads are
enabled, which is always the case for glibc but is a configure option
for uClibc.

We have solved this for internal toolchains by selecting the
BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this
option isn't available when ctng/external toolchains are used, mconf
prints ugly warnings and the build may fail if an external uClibc
toolchain without pthread debugging support is used.

Fix it by introducing 2 more hidden config options:
 - BR2_TOOLCHAIN_HAS_THREADS_DEBUG
 - BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED

The first tells us if the toolchain HAS pthreads debugging support,
and is checked by check_uclibc_feature in helper.mk for external uClibc
based toolchains.

The second tells us if the toolchain is ABLE TO provide pthreads debugging
support if threads are enabled, either because it's an internal toolchain
where we can force enable it or an external glibc/eglibc toolchain or
uClibc with the option enabled.

Crosstool-ng forcibly enables this support, so those will always work.
The preconfigured uClibc-based toolchains we have also all enable it.

Finally, show a comment if this isn't the case so the (external toolchain)
user knows why. This is placed outside the choice option, as menuconfig
has a bug where it doesn't show choice selections which only contain
comments.

b9882925a4 toolchain: introduce BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS
Unfortunately, the official Blackfin toolchains are built without the
shadow password support, so our default Busybox configuration fails to
build.

Therefore, we introduce a new hidden knob
BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS, which is set to yes for Buildroot
internal toolchain, for toolchains generated by the Crosstool-NG
backend, for Glibc external toolchains and for Uclibc custom external
toolchains. It is left unset by the Blackfin toolchain profile.

6c492d5e7b toolchain: add support for external toolchain profiles and download
Instead of letting the user define all the details of his external
toolchain, we define a set of profiles for well-known external
toolchains (CodeSourcery ones only at the moment, can easily be
extended with other toolchains).

Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.

We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no
profile is available.

We used to use different gdb configs for internal and external toolchains
because mconf won't source the same file twice. This works, but is kind of
sub optimal, as people forget to keep them in sync.

Fix it to use the same file for both situations by shuffling around the
config options a bit. Should work identical to before (except for the newer
gdb versions available for ext).
