Subject: [PATCH] Turn off lex by default on OpenBSD

Do the same as what AIX does. OpenBSD (at least recent ones) hits
below syntax error. Feel free to revert this commit and properly
fix this if possible.

CC y.tab.c
exp/expression-parser.y:68: syntax error
%parse-param { long long *result }
^
gmake: *** [Makefile:341: y.tab.c] Error 1
