 A patch for do_socket() in Linux user mode.
 The original code only handles socket constants conversion for target MIPS.
 We encountered this problem when emulating X86 apps on MIPS machines.
 This patch extends the scope to all targets and fix the problem.
 For your review, any comment is strongly welcomed.
