This commit adds a patch to gcc borrowed from CodeSourcery/Yocto that
warns about unsafe include paths (i.e /usr/include,
/usr/local/include, etc.). The patch was adapted to gcc arc-2014.08,
and modified to support the BR_COMPILER_PARANOID_UNSAFE_PATH
environment variable to error out instead of just warn when unsafe
paths are used. Even though erroring out can be chosen by passing
-Werror=poison-system-directories, we are not sure this option in
CFLAGS will always be passed, so having an environment variable
guarantees it will always be passed, and also allows to have an
identical behavior to the external toolchain wrapper.

Symptoms usually seen are like that:
--->---
Error: operand out of range (128 is not between -128 and 127)
--->---
where range may differ.
Since compiler tries to use jump/branch instructions with the shortest encoding
of offset it's important to calculate required offset properly.
In case of miscalculation by compiler later assembler throws an error because of
inability to encode requested value.
Fixes are taken from current development branch of GCC for ARC and will be a
part of the next release of ARC tools, so at that point patch should be dropped.

This commit adds a new patch to the ARC 2014.08 gcc specific version,
that redefines PTRDIFF_TYPE from "long int" to "int".
The change of SIZE_TYPE from "long unsigned int" to "unsigned int"
http://git.buildroot.net/buildroot/commit/?id=0f236c1fef669192c8f5cc8ef26e93da91438dc2
introduced a regression due to the existing PTRDIFF_TYPE.
Now to fix regression the patch converts PTRDIFF_TYPE to simple "int".
The fix is taken from current development branch of GCC for ARC and
will be a part of the next release of ARC tools, so at that point
patch should be dropped.

This makes size_t to be "unsigned" ssize_t which makes happy compiler on data
type checks.
Fix is taken from current development branch of GCC for ARC and will be a
part of the next release of ARC tools, so at that point patch should be dropped.

Now when new shiny tools are released by Synopsys we're ready for version
update in Buildroot.
Important change in this release is switching to combined "binutils-gdb" repo
in accordance to upstream move.
Following patch now is a part of the most recent relese:
e6ab8cac62
So dropping it.
package/binutils/arc-4.8-R3/0001-arc-Honor-DESTDIR-in-custom-Makefile.patch
Since arc-2014.08 tools are still based on GCC 4.8 following patch is still
relevant so moving to the new folder to matxh ARC gcc bump.
package/gcc/arc-4.8-R3/100-libstdcxx-uclibc-c99.patch ->
package/gcc/arc-2014.08/100-libstdcxx-uclibc-c99.patch
