The test calls `ldd` on `redis-server` in order to find out whether the binary
was linked against `libmusl`; However, `ldd` returns a value different from `0`
when statically linking the binaries agains libc-musl, because `redis-server` is
not a dynamic executable (as given by the exception thrown by the failing test),
and `make test` terminates with an error::
$ ldd src/redis-server
not a dynamic executable
$ echo $?

This commit fixes the test by ignoring such failures.
