[Asterisk-code-review] Build System: Fixes for configure script. (asterisk[master])

Corey Farrell has uploaded this change for review. ( https://gerrit.asterisk.org/8718


Change subject: Build System: Fixes for configure script.
......................................................................

Build System: Fixes for configure script.

* Replace all 'else if' statements with 'elif'.
* Use loop to detect versioned lua headers and libraries.

The loop for detecting lua fixes a bug where LUA_INCLUDE would be
appended with the directory of every lua version after the first one is
found.
