mips o32: fix 7th syscall argument with PTRACE_GET_SYSCALL_INFO API
As PTRACE_GET_SYSCALL_INFO API supports 6 syscall arguments,

(i.e. mips o32) have to fetch extra arguments manually when using
PTRACE_GET_SYSCALL_INFO API.

sockaddr: print sin6_flowinfo field before sin6_addr
The sin6_flowinfo field comes before sin6_addr in the sockaddr_in6

mips o32: fix build
Commit 917c2ccf3a67 "Refactor stack pointers" moved mips_REG_* macros
from linux/mips/arch_regs.h to linux/mips/arch_regs.c because these
macros are no longer used outside syscall.c or files included by
syscall.c, but this caused a build regression on mips o32 because
decode_syscall_subcall() uses mips_REG_SP prior to its definition.

Fix build for no-MMU targets
Commit 7488ce9e23f1 "Check whether PTRACE_GET_SYSCALL_INFO is supported

which is included in the main strace executable code. Although the
test_ptrace_get_syscall_info() routine is not called on no-MMU targets,
the compiler can't optimize it out because it is a global symbol.
So build for no-MMU targets currently fails:
