[PATCH] add AT_SUN_* constants to elf/common.h

There isn't one.  readelf does not decode NT_AUXV note contents at all.  
If I were to add that, the list of tags and descriptions would duplicate a
table I'll add to gdb.  So I'd rather either not touch readelf, or else put
this table into a shared source file (e.g. as a macro).
