#1412 seems related

@eworm-de if it isn't too much hassle for you, can you please rebase your PR against master? This might fix the travis checks.

Already did that before you requested. ;)

Is this still needed? It's rotting since 5 years and longer but things seems to work without that change.

For Arch Linux this works as we configure with --with-ping-command='/usr/bin/ping -4 -n -U -w %d -c %d %s' --with-ping6-command='/usr/bin/ping -6 -n -U -w %d -c %d %s'...

I guess this is be done by every maintainer. In Debian we do:

ifeq ($(DEB_HOST_ARCH_OS),linux)
PING_CONFIGURE_ARGS = --with-ping-command="/bin/ping -4 -n -U -w %d -c %d %s" \
                      --with-ping6-command="/bin/ping -6 -n -U -w %d -c %d %s"
else
PING_CONFIGURE_ARGS = --with-ping-command="/bin/ping -n -w %d -c %d %s" \
                      --with-ping6-command="/bin/ping6 -n -w %d -c %d %s"
endif

If nobody is complaining, I would prefer to close this one ...

Configuring at build time is the way to go.
