Justine Tunney d0ac995dc0 Get Mbed TLS to build 
This change configures Mbed TLS to support the fewest number of things
possible required to run an HTTPS server that caters to the sweet spot
of being legacy enough to support the vast majority of user agents but
modern enough that Chrome and Firefox remain happy. That should entail

- TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
- TLS_RSA_WITH_AES_128_CBC_SHA

Even though other suites still get included so what usually happens in
practice is ECDHE-RSA-AES256-GCM-SHA384 under TLS 1.2 will be selected
and the binary footprint is reasonable, and should cost us about 200kb

#
# 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
# o/dbg/examples/crashreport.com
# less examples/crashreport.c
#
# # extremely tiny binaries
# make -j8 -O MODE=tiny \
# LDFLAGS+=-s \
# CPPFLAGS+=-DIM_FEELING_NAUGHTY \
# CPPFLAGS+=-DSUPPORT_VECTOR=0b00000001 \

# 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.
