Comment # 22 on bug 96678 from Nicolai Hähnle

Valgrind has options --gen-suppressions and --suppressions to help with
suppressing unrelated errors. The first option will output suggested
suppression statements that need to be put into a file that can be loaded with
the suppressions option on a second run. Based on the Valgrind log, something
like

{
   <insert_a_suppression_name_here>
   Memcheck:Cond
  
obj:/home/user/.steam/steam/steamapps/common/Awesomenauts/Awesomenauts.bin.x86
}

should actually be sufficient as a suppression file.
