mate-panel-dbg 1.12.1-1 (powerpc binary) in ubuntu xenial

 The MATE Panel is an essential part of the MATE Desktop, providing
 toolbar-like “panels” which can be attached to the sides of your desktop.
 They are used to launch applications and embed a number of other
 functions, such as quick launch icons, the clock, the notification area,
 volume controls and the battery charge indicator, and utilities ranging
 from weather forecast to system monitoring.
 .
 This package contains the debugging symbols of the MATE panel application.
 .
 The debugging symbols are installed in /usr/lib/debug and will
 automatically be used by gdb.
