[cfe-dev] Building libc++ on Linux

When building libc++ on a clean Linux system (through cmake), it
complains that it can't find cxxabi.h. This is sensible because
cxxabi.h lives at /usr/include/c++/4.6/cxxabi.h, right next to all the
other C++ library headers, and the libc++ build passes -nostdinc++ to
avoid accidentally including those.
What's the right way to fix this? Options include:
1) Document that linux users should copy or symlink cxxabi.h from
their c++ include directory into /usr/include
2) Teach clang to find cxxabi.h in the C++ library directories even
3) Have the libc++ build process find cxxabi.h and copy it into the
libc++ include directory as part of the build.
