It comes from IRIX /usr/include/core.out.h, the
header which defines the IRIX core file format.

The 3 defines are
#define CORE_MAGIC      0xdeadadb0
#define CORE_MAGIC64    0xdeadad40
#define CORE_MAGICN32   0xbabec0bb

The initial struct in the core has a field with one of
the above values (which one depends on which ABI
the executable that coredumped was, of course).

CORE_MAGIC is for o32
CORE_MAGICN32 is for n32
CORE_MAGIC64 is for -64 (some people call it n64).

CORE_MAGIC was first, followed by CORE_MAGIC64, and then by
CORE_MAGICN32 over time. All 3 existed starting in the 
mid 1990's.
