Comment:
Could anyone who's familiar with C explain the error occuring on the ARM builds:
```
src/login.c:13:10: fatal error: security/pam_appl.h: No such file or directory

   13 | #include <security/pam_appl.h>

      |          ^~~~~~~~~~~~~~~~~~~~~

compilation terminated.
```
I think it means that there's a library that's not installed, but this error doesn't exist on any of the other architectures.
