re: toolchain/38512

    This is caused by the dependant .l and .y having a newer timestamp, so
    these files need to be moved to the DISABLED rule. Below is a local patch
    that is being used in house.

this patch is clearly the right thing.  i'll get it applied,
and similar other issues fixed up too.

thanks.
