Yes, Makefile is to be the wrapper for the gnatmake, gnatclean etc.
And configure is to just handle all the environment variables. If 
GNATLINKFLAGS variable is present (or if it's defined in config.site), 
then it will affect @GNATMAKEFLAGS@, etc.

I need to enumerate the variables expected to be respected. Different 
Ada packages respect different environment variables. For instance, some 
package might use ${ADAC} instead of ${ADA} as supposed.

But I might want to include some Objective C code in my packages.
