gas: xtensa: fix trampoline placement
For jumps requiring multiple trampolines trampoline placement code may place multiple sequential trampolines into the same frag. Don't do that. gas/ 2018-02-13 Max Filippov <jcmvbkbc@gmail.com> * config/tc-xtensa.c (xg_find_best_trampoline): Skip trampoline frag that contains source address.
