Comment (by kencu):

 I'm a bit confused about the aligned allocation flag need.

 Libcxx supports aligned allocations on all systems > 10.6 (ie that have
 posix_memalign) and possibly earlier systems with the additions I made to
 legacy support to add posix_memalign there.

 I have not seen errors related to lack of aligned allocation in libcxx on
 older systems that I can recall.

 There is a thing about a C11 aligned_alloc in clang:

 https://github.com/llvm/llvm-
 project/blob/0ed02621b9d87342daff0dcd9014319d4eeb2735/libcxx/include/__config#L939

 {{{
 #  if defined(__APPLE__)
 #    if (defined(__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__) &&
 \
          __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ < 101500)
 #      define _LIBCPP_HAS_NO_C11_ALIGNED_ALLOC
 #    endif
 }}}

 but that is supposed to be taken care of by the test in the block there...

 so I'm not sure what is going on with the need to disable aligned
 allocations in the previous commit.
