Increase build memory quota
If you install qemu-user from apt then glibc links a lot of address
space bloat that causes pthread_create() to ENOMEM (a.k.a. EAGAIN).
Boosting the virtual memory quota from 512m to 2048m will hopefully
future proof the build for the future, as Linux distros get fatter.
Please note this only applies to MODE=aarch64 on x86_64 builds when
you're using QEMU from Debian/Ubuntu rather than installing the one
cosmo provides in third_party/qemu/qemu-aarch64.gz. This change may
also be useful to people who are using the host compiler toolchain.

#
# SYNOPSIS
#
# Freestanding Hermetically-Sealed Monolithic Repository
#
# REQUIREMENTS
#
# You can run your programs on any operating system, but you have
# to build them on Linux 2.6+ (or WSL) using GNU Make. A modern C
# compiler that's statically-linked comes included as a courtesy.
#
# EXAMPLES
#
# # build and run everything
# make -j8 -O
# make -j8 -O MODE=dbg
# make -j8 -O MODE=opt
# make -j8 -O MODE=rel
# make -j8 -O MODE=tiny
#
# # build individual target
# make -j8 -O o//examples/hello.com
# o//examples/hello.com
#
# # view source
# less examples/hello.c
#
# # view binary
# o//tool/viz/bing.com o//examples/hello.com |
# o//tool/viz/fold.com
#
# # view transitive closure of legalese
# o//tool/viz/bing.com -n o//examples/hello.com |
# o//tool/viz/fold.com
#
# # basic debugging
# make -j8 -O MODE=dbg o/dbg/examples/crashreport.com

# # extremely tiny binaries

# UNSPECIFIED PREREQUISITES TUTORIAL
#
# A build rule must exist for all files that make needs to consider in
# order to build the requested goal. That includes input source files,
# even if the rule is empty and does nothing. Otherwise, the .DEFAULT
# rule gets triggered.
#
# This is a normal and neecssary behavior when source files get deleted.
# The build reacts automatically to this happening, by simply deleting
# and regenerating the dependency graph; so we can safely use wildcard.
#
# This is abnormal if it needs to keep doing that repeatedly. That can
# only mean the build config is broken.
#
# Also note that a suboptimal in-between state may exist, where running
# `make -pn` reveals rules being generated with the .DEFAULT target, but
# never get executed since they're not members of the transitive closure
# of `make all`. In that case the build config could be improved.
