Upstream fix for alignment bug in allocator start code

During the exp-run for bug 212343, lang/erlang-riak failed to build on i386 with clang 3.9.0, because beam.smp segfaults:

gmake[4]: Entering directory '/wrkdirs/usr/ports/lang/erlang-riak/work/otp_src_R16B02-basho5/lib/hipe/misc'
erlc -W  +debug_info +warn_exported_vars +warn_missing_spec +warn_untyped_record -o../ebin hipe_consttab.erl
gmake[4]: *** [/wrkdirs/usr/ports/lang/erlang-riak/work/otp_src_R16B02-basho5/make/i386-portbld-freebsd12.0/otp.mk:115: ../ebin/hipe_consttab.beam] Segmentation fault (core dumped)

This is because of an alignment bug in Erlang's threaded allocator, fixed by the following upstream commit:

https://github.com/erlang/otp/commit/5a00e724a58ee29d4012cca79c8aa33979e74eb6

Here is a patch for lang/erlang-riak to apply this.  The regular lang/erlang port already has the fix.
