You made the logical but invalid assumption that every toolchain works
the same. The "run" command is only available for some of the targets
for which RTEMS is cross-compiled. In particular, sparc-sis can be
executed by a simulator in gdb, which is what sparc-rtems4.11-run
wraps. 'tar sim' is available only when the gdb simulator support
exists.

For i386 the recommended simulator to use is Qemu.
