[Bug bootstrap/28784] New: [4.2 regression] Bootstrap comparison failure

["schwab at suse dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Since about 3 weeks bootstrap is failing due to comparison failure on
java/decl.o (no other object file is affected).  It first started with r115810,
then went away with r115850, but reoccurred with r115851.  Since then it
reoccurred often but irregularily.  Bootstrap is currently failing for three
days now.
When running the compilation command for java/decl.o manually the resulting
object file is identical to the stage2 object file, which means that there is
an environmental dependency in the generated code.  Bootstrapping with
--enable-checking=all didn't show any error, the comparison failure remained.
