[icedtea-web-1.0] RFC: Add configure output for jre tree detection

[Dr Andrew John Hughes]

This is just a simple patch to make the configure additions from Deepak's
previous jre detection addition print some output.

2010-02-01  Andrew John Hughes  <ahughes at redhat.com>

	* configure.ac: Call IT_CHECK_JRE_PREFIX macro
	rather than doing so inline.
	* acinclude.m4
	(IT_CHECK_JRE_PREFIX): Additions from configure.ac
	supplemented with configure output
	(AC_MSG_CHECKING/AC_MSG_RESULT).

Ok for 1.0?
