sim: bfin: lookup target strings when tracing system calls 

Parsing target addresses is hard if not generally useless, so use the new
cb_get_string function to lookup the associated strings as well.  Now the
trace output is quickly useful instead of just marginally so.

* interp.c (bfin_syscall): Increase _tbuf storage. Declare new local
tstr buffer. Call cb_get_string on tstr when handling CB_SYS_stat64,
CB_SYS_lstat64, CB_SYS_open, CB_SYS_write, CB_SYS_unlink,
CB_SYS_truncate, CB_SYS_rename, CB_SYS_stat, CB_SYS_lstat. Include
tstr in the tbuf output.

* Makefile.in: Delete all dependency rules.
