Fixes towards running in syscall emulation mode.
arch/sparc/linux/process.cc:
Fixed the assert and comment to check that the Num_Syscall_Descs is less than or equal to 284. Why does this assert need to exist anyway?
base/loader/elf_object.cc:
Cleared out comments about resolved issues.
cpu/simple/cpu.cc:
Use NNPC for both SPARC and MIPS, instead of just MIPS
configs/test/hello_sparc:
A test program for SPARC which prints "Hello World!"
