Enable compiling on GCC < 5 (#2149)
_ISOC11_SOURCE is the preprocessor flag that specifies whether or not aligned_alloc is defined and exists. While GCC versions lower than 5 do include C++11 and C++14 constructs, they do not include std::aligned_alloc, so this check allows compiling on those versions of GCC by defaulting down to posix_memalign in those situations appropriately.
