<pre>llvm 3.4 (branch) built with cmake "MinSizeRel" builds a llvm-config that does
not pass on "-DNDEBUG".
If 3rd party tools using LLVM rely on llvm-config for detecting a non-debug
build, this leads to errors.
E.g. it is impossible to use #include "llvm/Support/Debug.h" and use its
features in out-of-tree built passes, as that header references symbols that
are not built in llvm.
Also, e.g. if code on the line include/llvm/ADT/Statistic.h:156
(TsanHappensAfter(this);) is executed, a jump to a random address is executed
(valgrind states that: ==13931== Jump to the invalid address stated on the next
line)</pre>
