Subject: [PATCH] CodeSamples/formal/herd: Tame 'sort' command by setting LC_ALL
Otherwise, results of sorting in targets run-absperf and
run-absperf-all will depend on locale setting.
Fixes: ef392264b2b1 ("CodeSamples/formal/herd: Make use of absperf scripts in make targets")

Hi Paul,
I suppose your locale setting is "en_US.UTF-8".
If this is the case, the result of run-absperf with a short timeout
will look something like:
C-SB+l-o-o-u+l-o-o-u-X.litmus 0.04 0.04 0.04
C-SB+l-o-o-u+l-o-o-u-XE.litmus 0.09 0.09 0.09
C-SB+l-o-o-u+l-o-o-u+l-o-o-u-X.litmus 1.55 1.55 1.55

C-SB+l-o-o-u+l-o-o-u+l-o-o-u-CE.litmus 2.65 2.65 2.65

C-SB+l-o-o-u+l-o-o-u-CE.litmus 0.06 0.06 0.06
I used "sort -r" to have the ordering as:
C-SB+l-o-o-u+l-o-o-u.litmus 0.01 0.01 0.01
C-SB+l-o-o-u+l-o-o-u-XE.litmus 0.09 0.09 0.09
C-SB+l-o-o-u+l-o-o-u-X.litmus 0.04 0.04 0.04
C-SB+l-o-o-u+l-o-o-u-CE.litmus 0.06 0.06 0.06
C-SB+l-o-o-u+l-o-o-u-C.litmus 0.04 0.04 0.04
C-SB+l-o-o-u+l-o-o-u+l-o-o-u.litmus 0.06 0.06 0.06
C-SB+l-o-o-u+l-o-o-u+l-o-o-u-XE.litmus 5.26 5.26 5.26
C-SB+l-o-o-u+l-o-o-u+l-o-o-u-X.litmus 1.55 1.55 1.55
C-SB+l-o-o-u+l-o-o-u+l-o-o-u-CE.litmus 2.65 2.65 2.65
C-SB+l-o-o-u+l-o-o-u+l-o-o-u-C.litmus 1.22 1.22 1.22
C-SB+l-o-o-u+l-o-o-u+l-o-o-u+l-o-o-u.litmus 0.6 0.60 0.60
This change ensures the intended ordering no matter what your locale is.
(Well, this is not ideal, but close enough.)
Thanks, Akira
