mips: Remove rt_sigreturn usage on context function
Similar to powerpc, mips also issues rt_sigreturn for setcontext case the v0 value saved is not the one set by setcontext or makecontext. As for powerpc, it is intention is no really supported since setcontext is not async-signal-safe. Checked the context tests on mips64-linux-gnu and mips-linux-gnu. * sysdeps/unix/sysv/linux/mips/getcontext.S (__getcontext): Remove the magic flag store. * sysdeps/unix/sysv/linux/mips/makecontext.S (__makecontext): Likewise. * sysdeps/unix/sysv/linux/mips/swapcontext.S (__swapcontext): Likewise. * sysdeps/unix/sysv/linux/mips/setcontext.S (__setcontext): Remove rt_sigreturn call.
