[RFA] Build failure following COMMIT: Fix compile time error building i386-netware


On cygwin host, I get a build failure due to a warning about possible
use of uninitialized variable adjust in x86_cons.
 On that system, lex_got is a macro defined as NULL,
and thus does not set any value to adjust variable.


The patch below fixes that problem
Nick, could you check this in please?
