This commit is an update to Bugzilla 334836

There are two copies of the round test in none/tests/ppc32/round.c
and none/tests/ppc64/round.c.  The two source files should be
identical. The LE functional test commit updated the round.c test for
ppc64 but was missing the ppc32 round updates.  The round.c test was
updated to fix an issue where we were getting different outputs
depending on the compiler.  The output is now consistent for the
compilers allowing the removal of the additional expect files for
ppc32 and ppc64.
