PR #1200: absl/debugging/CMakeLists.txt: link with libexecinfo if needed

Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1200

`backtrace` and `execinfo.h` can be provided by libexecinfo on uclibc and musl resulting in the following build failure with any user of abseil-cpp (such as collectd):

```
/home/buildroot/autobuild/instance-0/output-1/host/lib/gcc/sparc-buildroot-linux-uclibc/10.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: /home/buildroot/autobuild/instance-0/output-1/host/bin/../sparc-buildroot-linux-uclibc/sysroot/usr/lib/libabsl_stacktrace.so: undefined reference to `backtrace'
```

[...]

```
    libgrpc++ . . . . . . no (libgrpc++ not found)
```

[...]

```
configure: error: "Some plugins are missing dependencies - see the summary above for details"
```
