mysqld_safe may incorrectly detect basedir when started as script

Details

    Description

      I want to debug mysqld_safe and start it as:

      bash -x -v mysqld_safe

      This typically results in error like below:

      2017-10-01 22:07:53 139934377842944 [Note] //sbin/mysqld (mysqld 10.1.28-MariaDB) starting as process 273 ...
      		 
      2017-10-01 22:07:53 139934377842944 [ERROR] Can't find messagefile '/share/mysql/errmsg.sys'
      		 
      2017-10-01 22:07:53 139934377842944 [ERROR] Aborting

      Suggested fix which works with bash , needs to be verified on other platforms:

      $ diff /usr/bin/mysqld_safe.old /usr/bin/mysqld_safe 
      520a521,526
      		 
      > if [ "$(uname)" == Linux ] && [ -n "$BASH_SOURCE" ] ; then 
      >   MY_PWD="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
      		 
      > else
      		 
      >   MY_PWD=`dirname $0`
      		 
      >   MY_PWD=`cd "$MY_PWD"/.. && pwd`
      		 
      > fi
      		 
      522,523d527
      		 
      < MY_PWD=`dirname $0`
      		 
      < MY_PWD=`cd "$MY_PWD"/.. && pwd`
