No Net::Ping test in building perl-5.16.3

[wavewave]

Due to some firewall restriction, Net::Ping tests while buiding perl caused failure with the following error:

Failed 6 tests out of 2173, 99.72% okay.
    ../dist/Net-Ping/t/120_udp_inst.t
    ../dist/Net-Ping/t/130_tcp_inst.t
    ../dist/Net-Ping/t/140_stream_inst.t
    ../dist/Net-Ping/t/150_syn_inst.t
    ../dist/Net-Ping/t/450_service.t
    ../dist/Net-Ping/t/510_ping_udp.t
### Since not all tests were successful, you may want to run some of
### them individually and examine any diagnostic messages they produce.
### See the INSTALL document's section on "make test".

This patch removes Net-Ping tests from perl source code base.

Please ignore poppler-glib patch in the above. Only the last one is relevant. Sorry for confusion.

Hmm, builders aren't supposed to access network, and in chroot builds it even isn't possible, which is what we're doing for Linux builds on Hydra. I wonder why the tests are skipped there and not for you.

Removing the test should do no harm, as we don't want to run it anyway. For testing/merging workflow, this is the same problem as #1633 (perl is inevitably stdenv-changing).

[wavewave]

Hmm, that's interesting. I thought it was due to the firewall as the name of the module (Net::Ping) suggested. I was testing this on AFS workspace on my machine which has a very strict firewall and SELinux. I am going to investigate errors further if I can have more information from verbose logs.

This appears to be subsumed by #1905, which will be merged soon as part of a series of stdenv changes. Please feel free to reopen if this is not covered by that one.
