build: Activate .DELETE_ON_ERROR.

Since m4 lacks the -o option to specify an output file, we redirect
stdout in several recipes, in particular in the recipe that creates
lopsub.h from lopsub.h.m4. If the m4 command fails, lopsub.h will
be incomplete or empty, yet it will be considered as up-to-date
by make(1).

This patch teaches make(1) to remove such incomplete output files
on errors.
