[PATCH] Add FreeBSD/i386 core file note support

[Mark Kettenis]

This patch adds support for FreeBSD/i386 core file notes.  The FreeBSD
notes are distinguished based on the name of the note, which has been
FreeBSD ever since support for ELF core dumps was first added to
FreeBSD.

OK to check this in?
