[Bug binutils/11131] New: Add updelfhdr

[hjl dot tools at gmail dot com]

I need to update machine type in ELF header. Objcopy doesn't work.
On Linux/x86-64, I got

address@hidden binutils]$ objcopy -O elf64-l1om /bin/ls ls
objcopy: Warning: Output file cannot represent architecture `i386:x86-64'

and no output was written. I wrote updelfhdr:

http://sourceware.org/ml/binutils/2009-12/msg00236.html

and got

address@hidden binutils]$ cp /bin/ls /tmp/
address@hidden binutils]$ ./updelfhdr --output-mach L1OM /tmp/ls
address@hidden binutils]$ readelf -h /tmp/ls
