Set awk and find used in run-octave from configure

[Moritz Borgmann]

To make run-octave run under Solaris, I propose the following patchset:

ChangeLog:

2007-12-03  Moritz Borgmann  <octave at moriborg.de>

	* Makeconf.in, aclocal.m4, configure.in: check for find 
program, preferably
	gfind (on non-GNU systems). Need a sane find for run-octave script.

	* run-octave.in: use FIND and AWK as determined by configure.
