Fix compilation of tests on alpine linux (musl libc)
If we don't link to libexecinfo, as detected by the
AC_SEARCH_LIBS(backtrace, execinfo) configure probe, we get
```
test-coredump-unwind.o: In function `handle_sigsegv':
/home/libunwind/tests/test-coredump-unwind.c:246: undefined reference to
`backtrace_symbols_fd'
collect2: error: ld returned 1 exit status
Makefile:1187: recipe for target 'test-coredump-unwind' failed
```
and
```
Gtest-init.o: In function `do_backtrace()':
Gtest-init.cxx:(.text+0x2f): undefined reference to `_Ux86_64_getcontext'
Gtest-init.cxx:(.text+0x48): undefined reference to `_Ux86_64_init_local'

collect2: error: ld returned 1 exit status
Makefile:1063: recipe for target 'Gtest-init' failed
```
There are 2 XFAIL and 6 FAIL tests, but it's a start
