[sane-devel] improved libcheck target

[stef]

	Hello,

	I have tried 'make libcheck' now it handles dynamic libraries. I notice it 
fails at the first violation without testing following libraries. I'd rather 
have it check all libraries then fail at the end so we get the full list of 
violations.
	BTW the offending symbols are:
stefdev:/home/stefdev/cvs/sane/sane-backends>make libcheck
