Log Message:
lint: remove explicit list of known GCC attributes

Most GCC attributes consist of a single identifier.  Up to now, it was
necessary to list each of these identifiers in the grammar, even those
that only apply to a single target architecture.

Instead, parse the general form of attributes, matching the few
attributes that lint handles by name instead.  While here, rename the
grammar rules to use the GCC terms.

To avoid conflicts between the global function 'printf' and the GCC
attribute of the same name, do not add GCC attributes to the symbol
table, and don't make these symbols 'extern' either.
