[Pvfs2-cvs] commit by pcarns in pvfs2-1: configure

[CVS commit program]

Update of /projects/cvsroot/pvfs2-1
In directory parlweb1:/tmp/cvs-serv688

Modified Files:
	configure 
Log Message:
Experimental fix to recent compile problems; copy the kernel makefile's
logic for detecting host arch and use it to add extra include paths for
configure tests.  Skip if user manually specifies ARCH for cross compile.

This needs testing.
