The sparc is big-endian, the x86 is little-endian.

Use od -b (octal bytes) and everything will look as expected.
If you've got hexdump on the sparc, use the script and format file
attached.  It will dump bytes in hex.

Dumping the 32-bit integer 0x76543210

x86:   0x10 0x32 0x54 0x76
sparc: 0x76 0x54 0x32 0x10
