[v3] let doxygen find generated header files

[Matthias Klose]

The current setup hardcodes i686-pc-linux-gnu in the doxyfile and lets
doxygen fail on other setups. Pass the current configuration from the
Makefile to run_doxygen and use it for doxygen.

Ok to checkin?

	* docs/doxygen/run_doxygen: Add --build_alias option,
	substitute it in docs/doxygen/user.cfg.in.
	* docs/doxygen/user.cfg.in: Use build_alias.
	* Makefile.am: Pass --build_alias to run_doxygen
	* Makefile.in: Regenerate.

           maint          Generate maintainers' HTML documentation (lots more;

+      BUILD_ALIAS is the GCC build alias set at configure time.

       more options when i think of them
