29f0662c18 Fix restarting after a complete build
It is much, much better to *first* make the directory writable and *then*
do a test for case-sensitivity (which requires writing in that directory).

Fixes #1033.

eef8eb4033 kconfig: display recursive dependency resolution hint just once
Commit 1c199f2878f6 ("kbuild: document recursive dependency limitation
/ resolution") probably intended to show a hint along with "recursive
dependency detected!" error, but it missed to add {...} guard, and the
hint is displayed in every loop of the dep_stack traverse, annoyingly.

This error was detected by GCC's -Wmisleading-indentation when switching
to build-time generation of lexer/parser.

scripts/kconfig/symbol.c: In function ‘sym_check_print_recursive’:
scripts/kconfig/symbol.c:1150:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
   if (stack->sym == last_sym)
   ^~
scripts/kconfig/symbol.c:1153:4: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
    fprintf(stderr, "For a resolution refer to Documentation/kbuild/kconfig-language.txt\n");
    ^~~~~~~

I could simply add {...} to surround the three fprintf(), but I rather
chose to move the hint after the loop to make the whole message readable.

c41b9641b1 package/gcc: fix xtensa PR target/65416
gcc-8.1 for xtensa miscompiles uClibc dynamic linker due to gcc PR
target/65416. The build completes successfully, but the binary is
non-functional because the following fragment in the _dl_get_ready_to_run
in ld-uClibc.so overwrites register spill area on stack causing register
corruption in the previous call frame and a subsequent crash:

    419f:       f0c1b2          addi    a11, a1, -16
    41a2:       1ba9            s32i.n  a10, a11, 4
    41a4:       0bc9            s32i.n  a12, a11, 0
    41a6:       5127f2          l32i    a15, a7, 0x144
    41a9:       1765b2          s32i    a11, a5, 92
    41ac:       4e2782          l32i    a8, a7, 0x138
    41af:       146af2          s32i    a15, a10, 80
    41b2:       001b10          movsp   a1, a11

The crash terminates the init process and causes kernel panic.
The fix prevents reordering of movsp opcode and any access to the stack
frame memory and is applicable to all existing gcc versions.

409046f91d ARC: Update Linux samples
There's no point in keeping samples which are in its essense
just a sub-set of multilib toolchain.

But still we'd like to cover quite unusual but really existing
case - ARC750, i.e. ARC700 with MMU but without so-called
atomic instructions (LLOCK/SCOND). To support this HW variation
we need:
 1) Compile all target binaries without "-matomics" or even
    better "-mno-atomics" so that's even future-proof
    (as we may decide to enable "-matomics" by default for Linux
     targets which is a recommented setup).
 2) Configure libc such that it uses Linux-kernel-assisted implementation
    of atomic operation via "arc_usr_cmpxchg" syscall,
    see https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=b985fa069187e4c5a7ee84213d9fbead2f219ce5

0a64056dd3 ARC: Disable CONFIG_ARC_HAS_ATOMICS in uClibc if building without -matomics
In case we build for ARC core which has no support of atomic ops among
other things we need to configure libc to use Linux kernel helper to emulate
HS atomic ops. This is done with disabling of CONFIG_ARC_HAS_ATOMICS in uClibc.

Currently we __remove__ this option from .config but this makes no sense as
its default state is "y" so we need to explicitly disable it instead.

ecb09ca417 ARC: Add multilib support for Linux in GCC
We never bothered to build multilibbed Linux toolchains for ARC
and so we ended-up with no support of multilib for arc*-*-linux-*
targets in GCC. That is now fixed in upstream by the following commit:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=0eacfbcb2bf1834294f468a2bb41fe5d5e8d3883

Once the fix mentioned above is applied on top of GCC 8.1.0 we may easily build
multilibbed uClibc toolchain for ARC.

Note sice Glibc port for ARC is still in review process we cannot build any Glibc
toolchains for ARC with pure upstream components, for that we eiter need Glibc
sources from our Github repo or apply a set of patches on top of Glibc 2.27 - we'll
try to address this later though.
