This fixes a recurring problem where patches that have only been
tested on MS toolchains break the build on GCC because they use
variables that are only written but never read.
However, there is a valid pattern where this may happen as well.
For instance,
Status = SomeFunc (&OutVar);
ASSERT_EFI_ERROR (Status);
if (Outvar == ... ) { ... }
// Status never referenced again
may never access Status again at all in RELEASE builds, since the
ASSERT_EFI_ERROR () macro evaluates to nothing in that case.
So let's allow this pattern, by passing the appropriate GCC command
line option.
