The latter is exactly what Makefile patch that brought this change
says, I think.

    # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
    # feature.

Before the series updated the message to the above, we used to say:

    # Define NO_REGEX if you have no or inferior regex support in your C library.

which _was_ unfair to those who needed to set NO_REGEX for whatever
reason.  It was totally unclear "inferior" relative to what standard
the message was passing its harsh judgement on your C library.
