[PATCH] uml: make UML_SETJMP always safe
If enable is moved by GCC in a register its value may not be preserved after
coming back there with longjmp(). So, mark it as volatile to prevent this;
this is suggested (it seems) in info gcc, when it talks about -Wuninitialized.
I re-read this and it seems to say something different, but I still believe
this may be needed.
