libjava/classpath/

	* lib/gen-classlist.sh.in: Avoid grepping each omission, by
	building an awk script with a hash for literal files, and
	awk regular expressions for the rest.
	* configure.ac: Call AC_PROG_AWK.
	* configure: Regenerate.

# We construct 'classes.1' as a series of lines. Each line
# has three fields, which are separated by spaces. The first
# field is the package of this class (separated by "/"s).
# The second field is the name of the top-level directory for
# this file, relative to the build directory. E.g., it might
# look like "../../classpath/vm/reference".
# The third field is the file name, like "java/lang/Object.java".
# We do this because it makes splitting for the gcj build much
# cheaper.
