Subject: [PATCH] Makefile.inc1: sysent: allow subordinate sysent targets to
 run in parallel

makesyscalls.lua (and indeed makesyscalls.sh) are both safe to be run in
parallel, so let's do it.

This is a trivial difference because runtime per-target is pretty small, but
I like seeing it run in parallel when my muscle memory types `make -sj4`.
