Re: Add tests that backtrace and backtrace_symbols produce correct results

You cannot expect reliable backtrace through a signal trampoline without
unwind information.

Obtained backtrace with 6 functions
Function 0: /daten/src/libc/m68k/debug/tst-backtrace4(handle_signal+0x1e) [0x800016f6]
Function 1: [0xeffff520]
Function 2: /daten/src/libc/m68k/debug/tst-backtrace4(fn+0x18) [0x800019c2]
Function 3: /daten/src/libc/m68k/debug/tst-backtrace4(fn+0x18) [0x800019c2]
Function 4: /daten/src/libc/m68k/debug/tst-backtrace4() [0x80001a40]
Function 5: /daten/src/libc/m68k/debug/tst-backtrace4(main+0x1e2) [0x80001466]
