Commit 9a93848fe787 ("x86/debug: Implement __WARN() using UD0")
rightfully removed GENERIC_BUG from UML because UML didn't use
that feature.
A side effect of this is that DEBUG_BUGVERBOSE no longer
set and therefore panic() doesn't print a stack trace.Let's select DEBUG_BUGVERBOSE manually to have a verbose panic() again.
