'''
This is a helper script. It runs ./configure (or cmake,
etc.) for you, setting the environment variables to use
emcc and so forth. Usage:

  emconfigure ./configure [FLAGS]

You can also use this for cmake and other configure-like
stages. What happens is that all compilations done during
this command are to native code, not JS, so that configure
tests will work properly.

Relevant defines:

  CONFIGURE_CC - see emcc

emconfigure is a helper for configure, setting various environment
variables so that emcc etc. are used. Typical usage:

  emconfigure ./configure [FLAGS]

(but you can run any command instead of configure)
