that's not generally true.  it depends on the target whether the sim supports 
Linux syscalls, dynamic libraries, etc...

the Blackfin sim certainly supports not only newlib/bare metal code (which also 
includes Linux/bootloaders), but also uClibc/FDPIC/FLAT Linux user programs.  
i've seen other sims in there that support Linux userland targets.

sounds like it should be made into a config option for people to control if 
*they* don't want the sim.
