toolchain: Bump ARC tools to arc-2018.09-rc1

This commit bumps ARC toolchain to arc-2018.09-rc1.
We want to test how new toolchain-rc1 builds packages,
so we can make fixes before release of toolcain.

ARC GNU tools of version arc-2018.09-rc1 bring some quite significant changes like:
* Binutils v2.31.1 with additional ARC patches
* GCC 8.2.1 with additional ARC patches
* glibc 2.28 with additional ARC patches

Please note that it is a release candidate and it might contain some
breakages, please don't use it for production builds.

-Subject: [PATCH] cilk: fix build without wchar
-
-When building against uClibc with wchar support disabled, WCHAR_MIN and
-WCHAR_MAX are not defined leading to compilation errors.
-
-Fix it by only including the wchar code if available.
