Bug#718655: [kfreebsd] git FTBFS: hang in tests

[Jonathan Nieder <jrnieder@gmail.com>]

Source: git
Version: 1:1.8.4~rc1-1
Severity: serious
Justification: build failure

From the build log on fano (kfreebsd-amd64):

 ok 16 - push --no-progress suppresses progress
 not ok 17 - quiet push
 #
 #		ensure_fresh_upstream &&
 #
 #		test_terminal git push --quiet --no-progress upstream master 2>&1 | tee output &&
 #		test_cmp /dev/null output
 #
 # failed 1 among 17 test(s)
 1..17
 make[3]: *** [t5523-push-upstream.sh] Error 1
 make[3]: *** Waiting for unfinished jobs....
 E: Caught signal ‘Terminated’: terminating immediately
 make[3]: *** [t0021-conversion.sh] Terminated
 make: *** [build-arch-stamp] Terminated
 make[2]: *** [test] Terminated
 make[1]: *** [test] Terminated
 Build killed with signal TERM after 150 minutes of inactivity

Likewise on finzi (kfreebsd-i386):

 *** t5709-clone-refspec.sh ***
 ok 1 - setup
 ok 2 - by default all branches will be kept updated
 ok 3 - by default no tags will be kept updated
 ok 4 - --single-branch while HEAD pointing at master
 E: Caught signal ‘Terminated’: terminating immediately
 wait: Interrupted system call.  Stop.

Other arches run the test suite without trouble.
