From ed06fade6dc46df0a38caab2e465dfaabfc76f46 Mon Sep 17 00:00:00 2001

Subject: [PATCH] nfs-utils: fix addrinfo usage with musl-1.1.21
Afer the update to musl 1.1.21 freeaddrinfo is broken in some places in
the nfs-utils code because glibc seems to ignore when freeaddrinfo is
called with a NULL pointer which seems to be not defined in the spec.
See: https://www.openwall.com/lists/musl/2019/02/03/4
The free in support/export/hostname.c is removed too
See: https://www.openwall.com/lists/musl/2019/02/17/2
Define and use wrapper function nfs_freeaddrinfo to handle
freeaddrinfo versions that don't tolerate NULL pointers
