  To: buildroot

As described at:
4520524ba055706236db9f00dd79f1b2e2e87fde
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//

Note that we added patch for uClibc-ng that also affects PIE feature.
We had to do that because in Buildroot for ARC uclibc comes right from
uClibc-ng release tarballs and the change hasn't been in any release of
uClibc-ng. If we don't add this patch we see a lot of link-time issues.
This patch is stopgap measure. We are going to upstream this change
to uClibc-ng and remove from buildroot as soon as it would be included
in some uClibc-ng release.

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.
