Description:
When libtool compiles mysqld and uses a wrapper in sql/mysqld that spawns .libs/lt-mysqld, the instance manager gets confused in Instance_options::fill_instance_version() because the first bit of the output of mysqld --version isn't the same as the path to mysqld.

How to repeat:
Run the instance manager on a box where libtool wraps executables.

Suggested fix:
Look for something less unstable, like 'Ver'.

Fixed in 5.1.10.

  Bug #19059: Failure to get version information when running from source tree
  
    Fix the way that instance manager finds the version number of instances,
    so that it works properly when the executable name isn't the same as what
    the instance-manager launched, such as when wrapping a libtool-wrapped
    executable from the source tree.
  
    This removes the 'Ver ' reported in the version column output by
    'SHOW INSTANCE STATUS ...', but the format of this column is not
    documented (and is pretty free-form to begin with).
