Subject: [PATCH 2/4] UML - Fix kernel vs libc symbols clash

commit 2a772652c3971745228a2e40e6575ae594c88365

uml: fix an IPV6 libc vs kernel symbol clash

On some systems, with IPV6 configured, there is a clash between the kernel's
in6addr_any and the one in libc.

This is handled in the usual (gross) way of defining the kernel symbol out of
the way on the gcc command line.
