Donald Sharp cae8bc967c *: Remove solaris from FRR 
The Solaris code has gone through a deprecation cycle.  No-one
has said anything to us and worse of all we don't have any test
systems running Solaris to know if we are making changes that
are breaking on Solaris.  Remove it from the system so
we can clean up a bit.
