[Buildroot] [git commit] package/nginx: disallow AIO support on arc

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=e935d6079f8d0d91a3ec6c5aba45c97de47f5c98
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The nginx AIO support cannot build on arc, because it hardcodes
the usage of SYS_eventfd(), while it should just use eventfd() from
the C library.

Fixes:

[Thomas: adjust comment as suggested by Yann.]
