Port strace to the Blackfin architecture.
* configure.ac: Add bfin to supported architectures.
* process.c: Skip u_fpvalid/u_fpstate for Blackfin architecture.
(change_syscall): Support Blackfin architecture.
* syscall.c: Declare r0 for Blackfin architecture.
(get_scno): Decode Blackfin syscall number.
(syscall_fixup): Extract Blackfin return value.
(get_error): Decode Blackfin return value.
(force_result): Poke Blackfin return value.
(syscall_enter): Extract Blackfin syscall arguments.
* defs.h: Define TCB_WAITEXECVE for Blackfin architecture.
* linux/syscall.h (sys_sram_alloc): Declare for Blackfin
architecture.
* system.c (sys_sram_alloc): Decode Blackfin sram_alloc() syscall.
* util.c (getpc): Handle PC on Blackfin architecture.
(printcall): Likewise.
* linux/bfin/ioctlent.h, linux/bfin/syscallent.h: New Blackfin
headers.
* Makefile.am (EXTRA_DIST): Add linux/bfin/ioctlent.h and
linux/bfin/syscallent.h.
