Re: [kirkstone 15/15] gcc-runtime: Pass -nostartfiles when building dummy libstdc++.so

Can we get this patch in ASAP? meta-zephyr (and layers that use it)
have been broken for weeks now in kirkstone, and I can confirm that
this patch fixes the issue.

Thanks,
Jon

This is a dummy shared object therefore reduce dependencies further by
not requiring the C startup files, we wont use this shared library for
anything useful anyway
