Re: [patch] buildcross trivial cleanup

[Bernhard Fischer <rep.dot.nop@gmail.com>]

misc trivia for em_build and related scripts:

	* conf_vars.sh: Let user specify FORCE_REBUILD
	* em_version.sh: Make check for equality of versions more
	robust.
	* em_build.sh: Test integers with integer ops.
	Fix test for FORCE_REBUILD (has to be a string comparison).

Please consider applying, TIA and cheers,
