Arnaldo Carvalho de Melo	7fee466676	libbpf: Define MFD_CLOEXEC if not available ... Since its going directly to the syscall to avoid not having memfd_create() available in some systems, do the same for its MFD_CLOEXEC flags, defining it if not available. This fixes the build in those systems, noticed while building perf on a set of build containers.

Arnaldo Carvalho de Melo	6816734203	libbpf: Define __WORDSIZE if not available ... Some systems, such as Android, don't have a define for __WORDSIZE, do it in terms of __SIZEOF_LONG__, as done in perf since 2012: http://git.kernel.org/torvalds/c/3f34f6c0233ae055b5 For reference: https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html I build tested it here and Andrii did some Travis CI build tests too.
