The current syscalls.c implements getpid/fstat/stat/link/unlink as mere
stubs. So replace them with useful calls to do_syscall now that our sim
can support them.

The sim lseek() syscall in the Blackfin libgloss code did not pass down
the "whence" argument making lseek() in general kind of useless.

The sim passes back results via two values, and the error code via a 3rd.
make sure libgloss extracts all three so that things like errno work as
expected. This fixes many gdb tests which look for this sort of thing.

Make sure gcc L1 attributes work with the default Blackfin linker scripts.
