[svn-r14470] Purpose: 	Fixing configure problem on IRIX64.

Description:	IRIX64 failed to build tools/h5import, as well as c++/test 
		with szip. This is because IRIX is very picky when it comes 
		to linking libraries, and must be done in specific order. 
		(other UNIXes are not as such, and thus the problem wasn't 
		present).

Solution:	Rearrange the order in which the libraries are
		linked on the compiler line by sorting the line that
		assigns libraries into the LDADD variable in the Makefile.am's
		of the two respective directories.

Tested:		IRIX64, kagiso, smirom
