Logfile of a failed build with poudriere.

Overview:
Both lang/ruby26 and lang/ruby27 fail to build with a jailed poudriere where the loopback interface has an address other than "127.0.0.1".

How to reproduce:
* On a FreeBSD 11.3 system, create a jail with a non-standard address on the loopback interface (such as 127.0.0.5).
* Install poudriere inside the jail.
* Build ruby26 using poudriere. The build-jails created by poudriere should also use some IP other than 127.0.0.1.

With this setup, Ruby fails to build succesfully with "poudriere bulk -j default -p default lang/ruby26". See the attached logfile for details of a recent attempt.

When poudriere is run in 'interactive' mode with "poudriere bulk -j default -p default -i lang/ruby26", it is possible to simply compile the port by running "make" inside the build-jail. Manually building the port inside a jail (even without a loopback address) also works. It only seems to fail whenever poudriere is used to perform the build.

Expected cause:
The "configuring socket" stage of the build compiles and runs a test program with getaddrinfo. At this point, a check is made if "127.0.0.1" exists (which isn't the case).
Such hardcoded loopback addresses are used in "ext/socket/extconf.rb":
    if (strcmp(straddr, "127.0.0.1") != 0) {
      goto bad;

If I understand correctly, this results in the build script trying to compile its own version of getaddrinfo (instead of using the one provided by the OS), which ultimately fails due to a conflicting function name (see the log).

No time to dig into this issue.
