It turned out that specifying all SRCS and INCS as dependencies on the pattern rules for all headers, caused `make` memory usage to skyrocket from 40mb ot 160mb. This change also reduces the build graph another 4%.

# 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.
|
