Issues with clang build

Hi,

         I am on r157251. When I try to build clang, I get this error.

Driver.cpp:52:47: error: use of undeclared identifier 'DEFAULT_SYSROOT'
    ClangExecutable(ClangExecutable), SysRoot(DEFAULT_SYSROOT),
                                              ^
1 error generated.
make[4]: *** [/home/ganapathy/projects/llvm/tools/clang/lib/Driver/Release+Asserts/Driver.o]
Error 1

Can someone help me with that ? Thanks
