Since this is a very special need by that test I don't like having to
add this to the general framework. The test can in fact get the path
to mysqld without argument with the help of this code snippet:

-------------------------
perl;
  my ($mysqld)= split " ", $ENV{MYSQLD_BOOTSTRAP_CMD};
  open(FILE, ">", "$ENV{MYSQL_TMP_DIR}/mysqld.inc") or die;
  print FILE "let \$MYSQLD= $mysqld;\n";
  close FILE;
EOF
source $MYSQL_TMP_DIR/mysqld.inc;
remove_file $MYSQL_TMP_DIR/mysqld.inc;
-------------------------

After this, $MYSQLD will be path to the executable with args stripped
off. OK it's more complex but it's also more localized to where it's used.
