[Buildroot] [git commit] toolchain: bump ARC toolchain components to arc-2015.12-rc1

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=e10860f644e5c09ee65c7c358e5e6059df94281e
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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:
