Mike Frysinger d4fa7379b0 libgloss: bfin: fix various warnings
No functional changes here, just fix warnings the compiler noticed.

bfin/syscalls.c:156:13: warning: conflicting types for built-in function ‘memset’

bfin/syscalls.c: In function ‘_unlink’:
bfin/syscalls.c:193:3: warning: passing argument 2 of ‘do_syscall’ discards qualifiers from pointer target type
bfin/syscalls.c:33:1: note: expected ‘void *’ but argument is of type ‘const char *’

bfin/syscalls.c: In function ‘_exit’:
bfin/syscalls.c:104:1: warning: ‘noreturn’ function does return

Michael Frysinger 1df99a60b3 libgloss: bfin: implement getpid/fstat/stat/link/unlink syscalls
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.

Michael Frysinger ecd3577e1d libgloss: bfin: fix sim lseek() syscall
The sim lseek() syscall in the Blackfin libgloss code did not pass down
the "whence" argument making lseek() in general kind of useless.

Michael Frysinger 4dfc786b8b libgloss: bfin: handle result2/errcode in sim syscalls
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.
