#define SIGSYS 12 /* non-existent system call invoked */

This is an unusual error to be getting, but it's possible that one of
the ports you tried to install tried to check for a syscall that either
doesn't exist or that you don't have enabled in your kernel (like the
POSIX realtime extensions, for example).  It might also be caused by
one of the linux-emulation ports trying to do something the Linux
compat code doesn't handle.  If all your ports built fine, don't worry
about it.

You can't find the corefiles because they would have been in the port's
work directory which gets cleaned up automatically during the upgrade.

Depends on what you want.  RELENG_5_3_0_RELEASE is a tag (not a branch)
that points to what got burned onto the 5.3 release CDs.  It doesn't
change.  RELENG_5_3 is a branch based off of 5.3, that will contain
only security fixes.  RELENG_5 is the -stable branch that will
eventually have 5.4, 5.6, etc branched from it.
