awk: fix race condition with sub-mk in mkfile
the maketab helper program was generated in parallel, which
had a dependency to y.tab.h which lead to yacc running
twice in parallel.
this removes the dependency to y.tab.h in the virtual
maketab.$objtype target to prevent this race condition.
the dependency to y.tab.h is resolved in the main mk at the
$cputype.maketab target which serializes with the other
targets.
