Return to syscall.h CVS log

Up to [local] / src / libexec / ld.so

ld.so should stop calling msyscall(2), since it is fully neutered and
about to be removed.  Please be careful building through this, you need
a kernel at least March 29th or so to build through it, otherwise use
snapshots to cross over.
ok various people
