Jordan Bancino 71a0181a6a Break out static options into an environment variable.
This allows users to turn off static compilation if the compiler or linker
throws a fit about it. Looking at you, Glibc. And PCC doesn't seem to like
static compilation either; it generates a binary that just segfaults
immediately on executation.

# A helper script that operates sort of like Make, except it is
# a lot easier to read and write than a Makefile, and it works on
# any POSIX system.
#
# I chose to use a custom build script instead of using Make because
# it is much more portable and flexible. This script doesn't only
# handle building the code, it also handles formatting it, as well
# as generating patch files.
#
# Set variables
#
# This syntax may look odd, but as far as I can tell, it is POSIX,
# and it allows the values to be overridden by the environment,
# such that these serve more as sane defaults than hard requirements.
