[Buildroot] [PATCH] autofs: allow to use libtirpc

[Waldemar Brodkorb]

uClibc-ng removed internal RPC implementation as it
is ipv4 only and can not be used for most important RPC software
rpcbind and nfs-utils.
musl does not implement RPC and GNU C library deprecated the
internal implementation a while ago.
It is still possible to use the C library implementation.

Applied to next, with a change. See below.

I've changed this to BR2_PACKAGE_LIBTIRPC=y, so that it gets used
whenever available, not only when the C library lacks RPC. We do this
in other packages, so I changed it for consistency.

Best regards,

Thomas
