# Contains the main cross compiler, that individually sets up each target build
# platform, compiles all the C dependencies, then build the requested executable
# itself.
#
# Usage: build.sh <import path>
#
# Needed environment variables:
# REPO_REMOTE - Optional VCS remote if not the primary repository is needed
# REPO_BRANCH - Optional VCS branch to use, if not the master branch
# DEPS - Optional list of C dependency packages to build
# ARGS - Optional arguments to pass to C dependency configure scripts
# PACK - Optional sub-package, if not the import path is being built
# OUT - Optional output prefix to override the package name
# FLAG_V - Optional verbosity flag to set on the Go builder
# FLAG_X - Optional flag to print the build progress commands
# FLAG_RACE - Optional race flag to set on the Go builder
# FLAG_TAGS - Optional tag flag to set on the Go builder
# FLAG_LDFLAGS - Optional ldflags flag to set on the Go builder
# FLAG_BUILDMODE - Optional buildmode flag to set on the Go builder
# TARGETS - Comma separated list of build targets to compile for
# GO_VERSION - Bootstrapped version of Go to disable uncupported targets
# EXT_GOPATH - GOPATH elements mounted from the host filesystem
# Define a function that figures out the binary extension
