Well we do have glibc port pretty much ready for ARC but it was not
yet accepted in upstream (being reviewed currently).

But if that's Ok I may [and it was on my todo list] to integrate
glibc for ARC with sources taken from
github.com/foss-for-synopsys-dwc-arc-processors/glibc.

We've got it integrated in both Buildroot and OpenEmbedded already
so it should work quite well.

Any thoughts?
