Subject: [PATCH 10/12] Tolerate a C library without NI_IDN

nss-server-info.cxx passes NI_NAMEREQD|NI_IDN to getnameinfo() when
resolving a compile server's host name.  NI_IDN is a GNU extension and
musl does not define it:

  nss-server-info.cxx:1971:55: error: 'NI_IDN' was not declared in this scope

Define it to 0 when absent.  The lookup still works; an internationalised
host name is just reported in its ACE ("xn--...") form rather than
decoded to Unicode.
