You can split your project to have 2 configure scripts. http://www.gnu.org/software/automake/manual/html_node/Subpackages.html http://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Subdirectories.html
You can either change the default compiler in configure.ac of your subpackage or you can create a proxy configure that alters the arguments passed from parent configure.
