Update readelf to know about the new ELF constants

[Nick Clifton]

Hi H.J.,

: Here is what I have today. EM_ALPHA is 41 and EM_ARC is 45. How about
: 
: #define EM_AVR        83   /* Atmel AVR 8-bit microcontroller.  */
: #define EM_FR30       84   /* Fujitsu FR30.  */
: #define EM_D10V       85   /* Mitsubishi D10V.  */
: #define EM_D30V       86   /* Mitsubishi D30V.  */
: #define EM_V850       87   /* NEC v850.  */
: #define EM_M32R       88   /* Mitsubishi M32R.  */
: #define EM_MN10300    89   /* Matsushita MN10300.  */
: #define EM_MN10200    90   /* Matsushita MN10200.  */
: #define EM_PJ         91   /* picoJava.  */

This seems reasonable.  Do I need to send these values to
registry@sco.com in order to make them official ?

Cheers
