This is not the correct fix. The fact that the toolchain used in the
build tests that failed does not have ifaddrs support is completely
unrelated to the fact that it's an ARC toolchain.

It's simply because this specific toolchain is an external toolchain
that doesn't have the ifaddrs support. The internal ARC toolchain will
have ifaddrs support, and other external toolchains may not have it.

So the right fix is to actually test whether ifaddrs support is
available or not. I've pushed a fix that implements this (hopefully
correctly) :
