Description
The function readdir_r has been deprecated in glibc since version 2.24 (see https://sourceware.org/bugzilla/show_bug.cgi?id=19056). Since hotspot wants to be compatible with glibc both older and newer than 2.24, the easiest thing for now is to ignore the warning. Later, if readdir_r actually gets removed in a future version of glibc, then we might have to fall back to e.g. dlopen to check if readdir_r is present. However, as long as readdir_r is "just" deprecated, then it easier to just disable the warning from gcc.
