ola: fix compilation of this package

This package does not currently compile.

This is needed to do so that it compiles:
- fix emptying CXX variable in configure script
- fix automake not generating Makefile (remove doxygen definitions)
- force gnu++11 by patch, does not work with configure variable
Also because of changed API in libmicrohttpd:
- fix HttpServer

Moreover this package does not support --disable-slp configure option
anymore, remove it.
