[LTP] [PATCH 1/1] rpc_test.sh: Check for rpcbind remote calls support

[Petr Vorel]

client binaries rpc_pmap_rmtcall and tirpc_rpcb_rmtcall require rpcbind
compiled with remote calls.  rpcbind has disabled remote calls by
default in 1.2.5. But this was not detectable until 1.2.8, which brought
this info in -v flag.

Detect the support and skip on these 2 functions when disabled.

Hi,

BTW it'd be nice to investigate why the broadcast functions fail,
enabling remote calls does not help, testing on:
./configure --enable-libwrap --enable-warmstarts --enable-debug --with-statedir=/run/rpcbind --with-rpcuser=rpc --with-systemdsystemunitdir=/usr/lib/systemd/system '--with-nss-modules=files usrfiles' --enable-rmtcalls

Kind regards,
Petr
