[Buildroot] [PATCH] utils/genrandconfig: filter microblaze GCC < 8 bug

[Matt Weber]

Works around https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180
which is an issue where the Microblaze archtecture had code that
caused a infinite recursion while optimizing in versions of GCC
less then 8.x.  More BR discussion can be found on this thread.

Note: I do not have a good way to test this.
