[PATCH] sparse: Add more ignored attributes

[Michael Buesch <mb@xxxxxxxxx>]

This adds more ignored gcc-style attributes.

externally_visible is a standard gcc attribute.
signal is an AVR8 attribute used to define interrupt service routines.

Ignore these attributes, as they are currently not useful for sparse checking.
