Jose Ricardo Ziviani 26920a2961 linux-user: fill target sigcontext struct accordingly 
A segfault is noticed when an emulated program uses any of ucontext
regs fields. Risu detected this issue in the following operation when
handling a signal:
  ucontext_t *uc = (ucontext_t*)uc;
  uc->uc_mcontext.regs->nip += 4;

but this works fine:
  uc->uc_mcontext.gp_regs[PT_NIP] += 4;

This patch set regs to a valid location as well as other sigcontext
fields.
