Comment (by sysfu):

 Using freshly extracted tor 0.2.7.2-alpha archive and the commands below
 it got bit further this time, before failing as per below. System is
 updated with LibreSSL 2.2.1

 Commands used:

 $ patch < tor-libevent2-4.patch
 $ env CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib ./configure
 --with-ssl-dir=/usr --disable-gcc-hardening --enable-bufferevents
 --disable-asciidoc
 $ AUTOCONF_VERSION=2.69 AUTOMAKE_VERSION=1.15 make check
