You've got a problem with compiling AddressSanitizer runtime: it
incorrectly defines "dirent" structure (normally it comes from
/usr/include/sys/dirent.h).
1) Which OS X version do you use?
2) What is the value of __DARWIN_64_BIT_INO_T on your system? (you may
check it by including sys/cdefs.h and looking at the value of this
definition).

Note that if you're not interested in ASan, you may just build clang as
follows:
"make -j10 ENABLE_OPTIMIZED=1 DISABLE_ASSERTIONS=1 clang"
