glibc: Add ARC architecture support to Glibc 2.30
This was generated from Synopsys GitHub Glibc WIP fork [1] this way:

git diff glibc-2.30..arc-2.30-2019.09.06 ':!NEWS' ':!ChangeLog'
----------------->8-----------------
[1] https://github.com/foss-for-synopsys-dwc-arc-processors/glibc
Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
[Updated to glibc 2.31: remove headers that became generic
(including pthread-offsets.h which had incorrect offsets copied
from 64-bit platforms), remove <asm/unistd.h> inclusion for
syscall numbers, GET_PC -> sigcontext_get_pc rename. Only
build-tested.]
