Nope.
I beleive it's standard.  I still remember Unices that did not have
syslog() at all, but no one that had syslog() without "%m".

FreeBSD xxx.xxxx.xx 4.10-STABLE
"The message is identical to a printf(3) format string, except that `%m'
     is replaced by the current error message."

SunOS xxxxx 5.7
"occurrences  of  %m  in  the  format
     string  pointed  to  by the message argument are replaced by
     the error message string associated with the  current  value
     of errno."

etc.
