[PING**2] [PATCH, libstdc++] Add missing free-standing headers to install rule

[Bernd Edlinger]

Hi,

I am pinging for this patch, which addresses an admittedly minor regression
for free-standing libstdc++ due to changed c++11 default settings.  The proposed
patch does only change the free-standing install rule, and has therefore no 
impact
on other configurations.

Thanks
Bernd.
