[yocto] [meta-darwin][PATCH] osx-runtime: OSX Yosemite v10.10

[Bystricky, Juro]

yes, I ran into the same libgcc problem, I plan on tackling it eventually. 
Likely some paths are not set correctly.
For what is worth, try to build the SDK against the poky "dizzy" branch.
I was able to build Darwin SDK with it. You may need to patch some other files though.
Anyway, there is new repo https://git.yoctoproject.org/cgit/cgit.cgi/meta-darwin-contrib/
where I will place some Darwin patches, most notably those I used to build 
the "dizzy" SDK (later next week).
