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

[Pavel Zhukov]

From: Khem Raj <raj.khem@gmail.com>

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
