On glibc x86-64, functions like pthread_cond_init exist in two versions:
2.2 (older pthread_cond_t) and 2.3.2 (newer pthread_cond_t). In glibc
versions prior to 2.36, using an unversioned interceptor
(`dlsym(RTLD_NEXT, "pthread_cond_init")`) retrieves the older 2.2
symbol, which is not desired
(https://sourceware.org/bugzilla/show_bug.cgi?id=14932).
For newer architectures, such as aarch64 (introduced in glibc 2.17) and
riscv64 (introduced in glibc 2.27), a versioned interceptor is
unnecessary.
