Justine Tunney 2d64b9994b Avoid creating temporary output files
This change also removes the futimens() call on the Landlock Make output
file workaround, since it caused problems with commands like fixupobj
which modify-in-place. It turns out if a file is opened for writing and
then no writes actually occur, then the modified time doesn't change.

# SYNOPSIS
#
# Cosmopolitan Core Build Rules
#
# DESCRIPTION
#
# This file shows GNU Make how to convert between file types, based on
# their extensions. We use everyday, ordinary, boring, and ubiquitous
# system commands for everything, e.g. as, cc, ld, etc. with plain and
# simple shell-script wrappers, e.g. build/assemble and build/compile.
# Those veneers abstract away most of the boring trivialities, to keep
# our makefiles pristine and readable.
