Could you please elaborate a bit on how do you build ARC toolchain?
That way we'll try to reproduce your problem locally.

Also may I ask you to try the very latest GCC and Binutils from 

GCC: https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/tree/dev
Binutils: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/tree/arc-2018.03

With these sources I can build everything successfully and run entire test-suite
with that following results:
-------------->8------------
Total skipped: 15
Total failed: 19
Total passed: 397
-------------->8------------
