[nfs-utils PATCH 1/1] Let the configure script find getrpcbynumber in libtirpc

[nfs-utils PATCH 1/1] Let the configure script find getrpcbynumber in libtirpc

[Petr Vorel]

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

The getrpcbynumber() function may not be available in the C library,
but only in the libtirpc library. Take this into account when checking
for the existence of getrpcbynumber() and getrpcbynumber_r().
