It's fairly well documented in portfile(7) under CONFIGURE OPTIONS and
in the Guide: <http://guide.macports.org/#reference.phases.configure>.

As cal said you can directly check what's being passed by default by
looking at the debug log. When dealing with non-autotools build systems
you often need to use some different variable names though.

If anything's missing from the docs we would welcome patches. :-)
The configure environment is set up in portconfigure::configure_main:
<https://trac.macports.org/browser/trunk/base/src/port1.0/portconfigure.tcl#L625>
and some variables are added for all commands in command_exec:
<https://trac.macports.org/browser/trunk/base/src/port1.0/portutil.tcl#L356>
