Patch to keep special sections generated by mips gcc

[Fred Fish]

New mainline versions of binutils ld strip zero length sections
by default.  This patch is needed to ensure that the special
sections generated by mips gcc are kept in the final executable.

	* mips/idt.ld, mips/idt32.ld, mips/idt64.ld, mips/nullmon.ld,
	mips/pmon.ld:  Keep special sections generated by mips gcc.
