[svn-r5042] Purpose:
	Bug Fix
Description:
	Some -I paths weren't included in the h5cc script. That would cause
	the compiler to fail if it was trying to find gass header files or
	the like.
Solution:
	Added the CPPFLAGS macro to the h5cc.in file so that it'll be there
	when it's generated. This will also include some -D options which we
	compiled the library with, like the LFS flags on Linux.

	Also changed the configure* files so that it will "chmod" the created
	h5cc file to 755 (executable) since that wasn't happening all the
	time...
Platforms tested:
	Linux
