Since GCC 9 and older fail to compile PR gold/31830 tests:
$ gcc -S testsuite/ver_test_pr31830_b.c -o /tmp/x.s
testsuite/ver_test_pr31830_b.c:3:1: warning: ‘__symver__’ attribute directive ignored [-Wattributes]
void __collector_foo_2_2(void) {}
^~~~
use asm statement, instead of symver attribute, for GCC 9 and older.
