build: avoid infinite recursions on include_next

On MacOS X 10.5 PPC with Apple's GCC 4.0.1:

building in place enters into an infinite recursion on "#include_next":

  Makefile:3414: recipe for target 'lib/math.o' failed
  gmake[2]: *** [lib/math.o] Error 1

Using -I./lib instead of -Ilib fixes the problem.

* Makefile.am (AM_CPPFLAGS): Use -I./lib instead of -Ilib.
