the directories that are searched are a fixed sheme so you can put together
your search list by adding the paths up

 * anything you specified with -l and --include-dir
   if it start with a slash - its an absolute path 
   else prepend the current directory (if the result exists)
 * standard search paths
   /usr/gnu/include
   /usr/include
   /usr/local/include
   PREFIX/include

so if you put all your -l and --include-dir into defined variables then 
add the standard paths you have your search path together and don't need 
to extract it from the MFLAGS or MAKEFLAGS.
