>Description:
	lint(1) is not currently cross-safe.  In particular, the lint
	binaries have machine-dependent parameters set at compile
	time -- see xlint/lint1/param.h.

	Also note -- those parameters are set based on CPP symbols
	provided by the HOST compiler.  That means that the lint(1)
	binaries produced are effectively targeted to the host.

>How-To-Repeat:
	Code inspection.

>Fix:
	Not provided.  Although, I have suggestions:

	(1) Properly target lint(1), and name the back-ends appropriately.
	    This would require changes to how param.h works ... the
	    Makefile would need to define TARGET_ARCH_whatever and
	    TARGET_OBJFMT_whatever (e.g. TARGET_ARCH_arm, TARGET_OBJFMT_ELF)
	    so that param.h can take appropriate action.

	...or...

	(2) Make lint(1) change its behavior based on environment variables,
	    such as TARGET_ARCH and TARGET_OBJFMT, looking up the behavior
	    to use in a table.

	(1) is probably the better solution (consistent with the
	    compiler).
