'''
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
