[svn-r9993] Purpose:
Bug fix

Description:
Arabica exhibited strange errors when linker found wrong versions of
header files.  This happened because include directories were
given to linker in the wrong order.

Solution:
Move include directories from AM_CFLAGS variable to INCLUDES
variable to put them before CPPFLAGS variable.  Trust me, it works.
This bug may also have contributed to strange errors on other platforms
(kelgia?).

Platforms tested:
copper, sleipnir, arabica.
	(h5dump broke while building on arabica, but this happened in
	a clean checkout, too).
