[PATCH] test for fegetround and fesetround

[Eshan Dhawan]

hello everyone,
I am new here and I sent the patches:
1. > https://lists.rtems.org/pipermail/devel/2020-February/057669.html
2. > https://lists.rtems.org/pipermail/devel/2020-February/057671.html
3. > https://lists.rtems.org/pipermail/devel/2020-February/057711.html
a few days ago.
for adding tests to psxfenv01.
but no one reviewed it.
so I ping it back
if someone could review it and give feedback.
