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

Browse Source 
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.
* ld/testsuite/ld-arc/tls-data-sections.s: New file.

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.
