Not all users of this header make use of all its variables.
For example vdso_test_correctness.c does not use "versions":
In file included from vdso_test_correctness.c:22:
vdso_config.h:61:20: warning: ‘versions’ defined but not used [-Wunused-variable]
61 | static const char *versions[7] = {
| ^~~~~~~~
Avoid those warnings through attribute((unused)).
