Bring benchmarks up to date with current simulator syntax and for current cross compiler

Bring benchmarks up to date with current simulator syntax and for current cross compiler:

• Some simulator syntax changes since the last time the benchmarks were updated (e.g., newnode syntax)
• Newest gcc is now for ELF on SuperH, and need to switch back from startup to main
• Newest C library optimizes strcpy using doubleword operations so doing strcpy or even memmove to transfer NIC_OUI breaks since the simulator assumes peripheral reads are byte reads.
• Other cleanup (no longer compress SPEC distribution files)
