Hi
"System svn"
I,m getting a make fail while trying to build clang in llvm. It gets
through to about 1300 and fails, scrolling back I find an error.
I have built llvm without clang and it succeeded, tried to rebuild llvm
with clang on exsisiting llvm failed.
I also tried on another fresh built LFS without an installed llvm same
fail.
So this fail seems to come from adding clang to the llvm build.

Try:
