Add Linux CentOS 7 infrastructure ports.

Mk/Uses/linux.mk changes:
- Add support for architecture neutral (noarch) distfiles.
- Add support for 64-bit only ports: set IGNORE on i386 and don't install
  32-bit compat libraries on amd64.

+libasyncns is a C library for Linux/Unix for executing name service queries
+asynchronously. It is an asynchronous wrapper around getaddrinfo(3),
+getnameinfo(3), res_query(3) and res_search(3) from libc and libresolv.
+
+In contrast to GNU's asynchronous name resolving API getaddrinfo_a(),
+libasyncns does not make use of UNIX signals for reporting completion of name
+queries. Instead, the API exports a standard UNIX file descriptor which may be
+integerated cleanly into custom main loops.
+
+In contrast to asynchronous DNS resolving libraries like libdenise, skadns,
+adns, libasyncns is just an asynchronous wrapper around the libc's synchronous
+getaddrinfo() API, which has the advantage of allowing name resolution using
+techniques like Multicast DNS, LDAP or NIS using standard libc NSS (Name
+Service Switch) modules. libasyncns is compatible with IPv6 if the underlying
+libc is.
+
+libasyncns is very tiny, consisting of just one header and one source file. It
+has no dependencies besides libc.
