Could you show this ./configure line:
checking for Linux AIO support ...
?

Probabaly, your kernel does not support eventfd(), it's available since
2.6.22 only.

BTW, instead of

         location ~* ^\/files\/(.+) {
             alias /home/files/$1;

it's better to use just

         location /files/ {
             root /home;
