Comment (by meitar):

 I have a tiny bit more info, shared in the hopes this squeaky wheel gets a
 bit more grease.

 Just today, I also hit the `socketpair_ersatz` test failure while building
 Tor on Raspbian. The relevant snippet of output from `debuild -rfakeroot
 -uc -us` is:

 {{{
 util/socketpair_ersatz: [forking]
   FAIL ../src/test/test_util.c:5526: assert(0 OP_EQ socketpair_result): 0
 vs -110
   [socketpair_ersatz FAILED]
 }}}

 This single test is the only one that failed. (In my case today, 31 other
 tests were skipped).

 The version of Tor I attempted to build was 0.3.4.8. My Raspberry Pi's
 `uname -a` output:

 {{{
 Linux raspberry 4.14.73+ #1148 Mon Oct 1 16:41:23 BST 2018 armv6l
 GNU/Linux
 }}}

 This was an
 [https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2835/README.md
 original Raspberry Pi with a BCM2835 chip].

 I believe this is a regression since I have been able to build prior
 versions of Tor successfully on this same physical device.

 Thanks again for all that you do.
