toolchain: bump ARC toolchain components to arc-2015.12-rc1

This change introduces newer ARC toolchain in Buildroot.
Note this is the first release candidate and we'll probably see another
RC before cutting the final release.

That new arc-2015.12 release doesn't bring any significant changes but
mostly is focused on fixes and minor improvements here and there.
Most noticeable changes are:
 * GCC updated to v4.8.5
 * GDB updated to 7.10

You may find more info on fixes and improvements in that release at:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2015.12-rc1

-Subject: [PATCH 1/2] ld/arc: Provide the .tdata symbol.
-
-When creating local dynamic tls access we rely on a .tdata symbol being
-available to link against.  Normally, this is fine, as content is placed
-into the .tdata section the linker makes a .tdata symbol available and
-all is fine.
-
-However, these linker created section symbols only exist for input
-sections, not output sections, so, when we assemble with
--fdata-sections, and the content is placed not into '.tdata', but into
-sections like, '.tdata.variable' we end up in a situation where there is
-no input section called '.tdata', and so the linker does not create a
-symbol called '.tdata' for us, at which point the link fails.
-
-The solution it to have the linker script explicitly provide the symbol
-'.tdata', this should ensure that the symbol is always available.
-
-ld/ChangeLog:
-
-	* scripttempl/arclinux.sc (.tdata): Provide the .tdata symbol.
-
-ld/testsuite/ChangeLog:
-
-	* ld/testsuite/ld-arc/arc.exp: Run new test.
-	* ld/testsuite/ld-arc/tls-data-sections.d: New file.

-Subject: [PATCH] Differentiate between a bss TLS initialized symbol.
-
-Back-port from https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/commit/366cc86e4f8ff6f00f0b731dc6f78d22c7ac9e0a
-
-This patch fixes "undefined reference to .tdata" observed in many autobuilder
-results for ARC.
-
-Once the next release of ARC GNU tools happens this patch must be removed from
-Buildroot.
