The Linux kernel doesn't even support i386 anymore, there is no NPTL
support for i386 and uClibc-ng only supports NPTL on x86, so there is
essentially no usable thread implementation. Most likely glibc and
musl also don't support i386 either. So it's time to remove the
support for this architecture variant.

The context functions in uClibc unconditionally use the classic ARM
instruction set.
On platforms that do support the ARM instruction set, there is no problem -
However, on platforms that only support the Thumb instruction set, the
context functions cannot be built since the assembler code is not
Thumb-ready. Therefore, these functions must be disabled on such
platforms. All Thumb1 platforms support ARM instructions, so this is
only relevant for Thumb2-only platforms (i.e., Cortex-M).
Note that some packages require the context functions, so these will
fail to build on these platforms. It is worth mentioning that musl
also doesn't provide the context functions, and those are rarely
used. Affected packages will be handled in later patches.

As explained by Waldemar, enabling DOPIC in uClibc will lead to the
creation of a Position Independent library. In turn, this will cause
elf2flt to generate a "Has-PIC-GOT" flat binary, which doesn't work on
ARM. In fact, elf2flt on ARM really expect to have non-PIC code as
input, so we must disable DOPIC in the uClibc configuration.

This commit adds a number of patches to uClibc that radically
simplifies the Thumb handling. uClibc currently has three options that
you need to toggle on Thumb configurations depending on the specific
ARM CPU being targeted.
However, it turns out that none of those options are necessary:
- USE_BX can simply be guessed by looking at the ARM core being
used. The bx instruction is available for all ARM cores >=
ARMv4T. This is exactly what glibc is doing.
- USE_LDREXSTREX can also be guessed by looking at the ARM core being
used: whenever you have Thumb2, ldrex/strex is available.
- COMPILE_IN_THUMB becomes useless, since all it does is passing
-mthumb. But just like the uClibc config options to set
--march=<foo> have been removed a long time ago, there's no need to
-have an option to pass -mthumb.

As recently reported on the mailing list:
http://lists.busybox.net/pipermail/buildroot/2016-February/154130.html
Our configuration options to use sha-256 / sha-512 password encoding do not
work very well with uClibc-ng as our defconfig doesn't enable support for
these encodings, breaking E.G. password login with dropbear.
Notice that it doesn't break login with the busybox login applet, as we
currently force the use of the internal busybox password handling routines
when sha-256/512 encoding is used. This workaround can afaik now be removed.
To fix this, enable support for these password encodings in our defconfig.
Do it unconditionally and not based on BR2_TARGET_GENERIC_PASSWD_* so it
also works when a Buildroot toolchain is reused as an external toolchain and
as the support code is quite small (~8KB):

For quite some time all ARC changes have been pushed upstream.
So both uClibc master branch and uClibc-ng have full ARC support
including the most recent changes.
I.e. finally we have reached the point when there's no need in
Synopsys fork of uClibc on GitHub and it will soon be obsoleted and
removed at some pint of time.
Now since vanilla uClibc hasn't seen any releases for many years we cannot
really use it for ARC. Fortunately there exists uClibc-ng and Waldemar
cuts releases regularly - that works perfectly fine for us.
That patch removes all mentions of ARC's uClibc which in turn makes
uClibc-ng default libc for ARC.

Recently uClibc got support of "savedefconfig" target that allows
generation of compact configuration description which only lists
differences from default options.
That's uClibc commit -
http://git.uclibc.org/uClibc/commit/?id=e286a674419d31cb0757dd2f8307d8b4756cf1f9
This change represents post-processing of "uClibc-snapshot.defconfig"
and "uClibc-ng.config" with "make savedefconfig" made on current
uClibc/master and uClibc-ng/1.0 branches accordingly.
Unfortunately the most recent stable uClibc version 0.9.33.2 doesn't
have "savedefconfig" target so I'm leaving uClibc-0.9.33.config as it
is.

Modern ARC cores (those sporting MMU of version 3 and 4) allow selection
of different page sizes (4, 8 or 16 kB) during ASIC design creation.
And it's important to build a toolchain with page size setting that matches

Otherwise user-space applications will fail on execution due to
unexpected data layout/alignment etc.

Even though this is only RC1 it's been heavily used internally so it should
not be any worse than existing arc-2014.12.
Moreover this relase (and so its RC1) finally delivers support of NPTL
for ARC in uClibc.
That's why it would be good to allow interested users to start trying it
(for example WebKit and apps that use WebKit could be successfully built
and run) also it will be helpful to run that new toolchain through
autobuilder in attempt to find any hidden regressions so we have a solid
toolchain for release.
If there's an interest in that patch more patches will follow with
subsequent RCs and essentially on appearence or relese Buildroot will be
