Patch for a29k warnings

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

This patch kills the following warnings from a sparc-sun-solaris2.7
cross to a29k-unknown-rtems using the latest snapshot as the host
compiler.

 > insn-attrtab.c:1172: warning: unused parameter `delay_insn'
 > insn-emit.c:1780: warning: function declaration isn't a prototype
 > insn-emit.c:1867: warning: function declaration isn't a prototype
 > insn-emit.c:2039: warning: function declaration isn't a prototype
 > insn-emit.c:2126: warning: function declaration isn't a prototype
 > toplev.c:2241: warning: initialization discards qualifiers from pointer target type
 > toplev.c:2241: warning: assignment discards qualifiers from pointer target type
 > varasm.c:226: warning: function declaration isn't a prototype

In addition to the cross compile, I also did a full bootstrap on
sparc-sun-solaris2.7, no testsuite or warning regressions.

Okay to install?

	* a29k-protos.h (literal_section): Prototype.
	* a29k.h (ASM_FILE_START): Don't discard pointer qualifier.
	* a29k.md: Ensure function pointers are prototyped.
	* genattrtab.c (write_eligible_delay): Mark parameter with
	ATTRIBUTE_UNUSED.
