The Nios-II Sourcery external toolchain (the only Nios-II we currently
support) exports broken kernel headers. In particular, these kernels should
be exported using the "headers_install" rule which applies a set of fixes
on the kernel headers so they are suitable for userspace usage.
In order to fix this, add a post-install hook to perform the header fixes
ourselves. The result is equivalent to apply the "headers_install" rule.

Old toolchains, with old gcc that do not support -print-sysroot, break the
kernel-headers version check script: it fails to find the sysroot of the
toolchain, and thus ends up including the host's linux/version.h.
Most of the time, this will break early, since the host's kernel headers
will not match the toolchain settings.
But it can happen that the check is succesful, although the configuration
of the toolchain is wrong:
- the custom toolchain has kernel headers vX.Y
- the user selected vX.Z (Z!=Y)
- the host has headers vX.Y
In this case, the check passes OK, but the build of some packages later on
will break (which is exactly what those _AT_LEAST_XXX options were added to
avoid).
Fix that by passing the sysroot to the check script, instead of the cross
compiler.
We get the sysroot as thus:
- for custom toolchains, we use the macro toolchain_find_sysroot. We can
do that, because we already have a complete sysroot with libc.a at that
time.
- for internal toolchain using a custom kernel headers version, we just
use $(STAGING_DIR). We can't use the macro as for custom toolchains
above, because at the time we install the kernel headers, we do not yet
have a complete sysroot with a libc.a. But we can just use
$(STAGING_DIR), since we're only interested in the kernel headers.
For all other types of toolchains, we already have the _AT_LEAST_XXX options
properly set, so we need not add a check in this case.

Since we introduced the _AT_LEAST_XXX for the kernel headers, people
using pre-built custom toolchain now have to specify the version of
the kernel headers their custom toolchain uses.
So, when we detect that there is a mismatch between the selection in
the menuconfig, and the actual version of the headers, we currently
only bail out with a terse message "Incorrect selection of kernel
headers".
This could be confusing some, and getting the version of the headers
used by the toolchain is not trivial (well, it's very easy, but not
trivial.)
This patch changes the way we report the error by moving the message
into the test-code, and by printing the expected and actual versions
of the kernel headers.
BUT! To get this pretty error message, we need to run the
test-program, so we can not use the cross-toolchain, we have to use
the native one.
BUT! The native one has its own linux/version.h header, so we can not
simply include it.
So, we ask the cross-compiler where its default sysroot is, and use
that to then force-feed the cross linux/version.h to the native
toolchain.
[Thomas: augment commit log with a message provided by Yann, fix
coding style to not have spaces after opening parenthesis and before
closing parenthesis, reformatted the message "Incorrect selection..."
to make it fit on one line.]

Ensure the kernel headers version used in the custom external toolchain,

selected by the user.
We do not care about the patch-level, since headers are not supposed to
change between patchlevels. This applies only to kernels >= 3.0, but
those are actually the ones we do care about; we treat all 2.6.x kernels
as being a single version, since we do not support any 2.6 kernels for

As our architecture support expands to a number of architectures that

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

In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.
A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

In our wrapper, we forcibly add the -march=, -mcpu= and-mtune= flags
to the actual compiler, this in an attempt to always generate correct
and optimised code for the target.
But in some cases, the caller knows better than we do, and passes its
own set, or subset of those flags. In this case, some may conflict with
the ones we pass. The most prominent offender being the Linux kernel.
For example, on the ARM Raspberry Pi, the Linux kernel will set the
-march=armv6 flag and no -mcpu= flag, but we pass -mcpu=arm1176jzf-s,
which conflicts:
drivers/scsi/scsi_trace.c:1:0: warning: switch -mcpu=arm1176jzf-s
conflicts with -march=armv6 switch
(and so for all the files the kernel compiles, pretty messy)
(note: arm1176jzf-s is not an armv6, it is an armv6zk. Yeah...)
To avoid this situation, we scan our commandline for any occurence of
the possibly conflicting flags. If none is found, then we add our owns.
If any is found, then we don't add any of our owns.
The idea behind this is that we trust the caller to know better than
we do what it is doing. Since the biggest, and sole so far, offender
is the Linux kernel, then this is a rather safe bet.

In a1d94aaa3a ('toolchain-external: add support for musl C
library'), we made the following change to the SYSROOT_DIR mangling
logic:
- SYSROOT_DIR=`echo $${LIBC_A_LOCATION} | sed -r -e 's:usr/lib(32|64)?/(.*/)?libc\.a::'` ; \
+ SYSROOT_DIR=`echo $${LIBC_A_LOCATION} | sed -r -e 's:(usr/)?lib(32|64)?/(.*/)?libc\.a::'` ; \
This was needed to accomodate for musl based toolchains that don't
have libc.a in usr/lib/..., but directory in lib/... Basically, the
change makes the usr/ at the beginning optional.
However, with the very permissive (.*) matching in the middle of the
path, the change above had an unexpected consequence: any path contain
'/lib' would be truncated before this lib. As an example, Peter
reported that his builds, running from /var/lib/buildbot/ were no
longer working because the SYSROOT_DIR was decided to be /var instead
of something like
/var/lib/buildbot/buildroot/output/host/opt/ext-toolchain/arm-linux-gnueabihf/libc/.
So, this commit changes (again!) this regexp by changing (.*) to
([^/]*), the idea being that it will match only *one* path
component. Note that this intermediate (.*) directory was added in
e6e60becb0 ('external-toolchain: add support for Linaro 2012.01') to
accomodate for Linaro toolchains that have a subdirectory in their
sysroot named after the target tuple:
$ ./output/host/opt/ext-toolchain/bin/arm-linux-gnueabihf-gcc -print-file-name=libc.a
/home/thomas/projets/buildroot/output/host/opt/ext-toolchain/bin/../arm-linux-gnueabihf/libc/usr/lib/arm-linux-gnueabihf/libc.a

In 11ec38b695 ("toolchain-external: fix Linaro ARM toolchain

a /lib/arm-linux-gnueabihf -> /lib symbolic link. This is needed
because the dynamic loader looks for libraries in
/lib/arm-linux-gnueabihf rather than the usual /lib, but Buildroot
installs all libraries in /lib.
However, we forgot that the dynamic loader also loads libraries from
