The latest llvm trunk (llvm 10) built require c++14.
Built with gcc and llvm 10 headers, the following
error will show up:
...

/home/yhs/work/llvm-project/llvm/build/install/include/llvm/Support/RWMutex.h:101:8:
error: ‘shared_t$
med_mutex’ in namespace ‘std’ does not name a type
std::shared_timed_mutex impl;

error: ‘is_final’ is not a member of ‘std’
static_assert(std::is_final<BaseTy>(), "BaseTy must be final.");
...
std::shared_timed_mutex and std::is_final etc. are all c++14 features.

Makefile now.
