Build raise with -fasynchronous-unwind-tables.
In testing glibc for Arm and MIPS, I see: FAIL: misc/tst-sigcontext-get_pc If this test - backtracing through a call to raise - is valid, then raise needs to be built with -fasynchronous-unwind-tables (as the test itself is) to have the required unwind information for that backtracing to work. Adding that option, which this patch does, causes the test for pass for Arm. For MIPS, the test still does not pass (the backtrace has an address that is 2 bytes after the "address in signal handler", for unknown reasons), although the patch allows a longer backtrace to be produced.
