[oe] [meta-oe][PATCH 5/6] mongodb: Fix build with clang

[Vincent Prince]

Hi Khem,

I can't compile mongodb in Warrior branch with g++ either,
it fails in boost::asio with std::basic_string_view with "-std=c++14"
cflags.
It seems C++17 support is only present in 4.1.x branch and not in r4.0.6?
Maybe we need to generalize this patch?

Regards,
Vincent
