[PATCH] Make large enum constants unsigned

Hi,

this fixes a bug noted in two threads on the binutils mailing list:
https://sourceware.org/ml/binutils/2014-05/msg00152.html
https://sourceware.org/ml/binutils/2014-05/msg00195.html

Both threads describe the problem pretty well, but the gist of it
is that constants are generated that will be interpreted as signed.

	* enum.scm (gen-enum-decl): Emit 'ULL' after constants larger than
	 #x80000000
