Originally reported as https://bugs.gentoo.org/763618 by Yoshihiko Iwama where static linking of a binary for initramfs fails on alpha:

```c
$ cat a.c
#include <sys/types.h>
#include <sys/time.h>
#include <sys/resource.h>
#include <sys/wait.h>

int main() {
    pid_t pid = 1;
    int wstatus;
    int options;
    struct rusage ru;
    return wait4(pid, &wstatus, options, &ru);
}
$ alpha-unknown-linux-gnu-gcc a.c -o a
$ LANG=C alpha-unknown-linux-gnu-gcc a.c -o a -static
/usr/libexec/gcc/alpha-unknown-linux-gnu/ld: /tmp/cciRui2f.o: in function `main':
(.text+0x40): undefined reference to `wait4'
collect2: error: ld returned 1 exit status
```

The suspect is https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=09153638cfef9166586b0c21e852ea0d6f15a0fd that misses static library handling.
