I think I found it, see below:

Notice the "-I -c -o ..." sequence

"-I" expects an argument which is an include directory, in this case 
it's missing and the "-c" is eaten by the -I so gcc ends up interpreting 
this as a compile+link command (default behavior). Since the required 
dependencies to link php_mapscript.c are not provided you get those 
linker errors.

You need to identify which configure option ended up inserting "-I" 
without the required arg ... look in your configure output, or in the 
main Makefile...
