configure: add options ability
There are more and more global environment variables that land everywhere
in configure, which is making user hard to know which one does what.
Using command-line options would make it easier for users to learn or
remember the config options.
This patch converts the INCLUDE variable to command option first. Check
if the first variable has '-' to compile with the old INCLUDE path
setting method.
