xtensa_sigtramp.S: Remove the ENTRY instruction.
_xtensa_sig_trampoline is returned to after a context switch and not called
by the usual Window call instructions (call4, call8 and call12),
thus does not need the entry instruction. Furthermore, the ENTRY instruction
in this case is messing up the backtrace as it creates an extra frame.
