I like to use my first name only. I have configured that to most of places.
I don't think I need commit rights. I hope that cmake build system
will require very little changes to packaging.

I tested the packages using my own project test suit that uses clang++
to compile.

-lc++ shouldn't be included for libc++abi. I didn't see that appearing
in my system. Full log could help figure out what went wrong.
