Title:
  FTBFS: tests fail on s390x due to incorrect regexp on /proc/cpuinfo

Status in git package in Ubuntu:
  Fix Released
Status in git package in Debian:
  Fix Released

Bug description:
  git commit 29fb2ec384a867ca577335a12f4b45c184e7b642, present in 2.38.0
  and later, introduced a function that gets the number of cores from
  /proc/cpuinfo. It essentially does this:

      do { local @ARGV='/proc/cpuinfo'; return
  scalar(grep(/^processor\s*:/, <>)); } if -r '/proc/cpuinfo';

  On s390x, the ^processor lines are like this:

  processor 0: version = FF,  identification = 148F67,  machine = 2964

  In other arches (I checked amd64, armhf and arm64), they are like this
  instead:

  processor       : 0

  As a result, that function is returning 0 on s390x, and that value is
  used for the number of jobs the script should execute. Since it's
  zero, it exits without doing anything, and that breaks the test and
  the build[3] on s390x.
