[PATCH] Keep special sections generated by mips gcc

[PATCH] Keep special sections generated by mips gcc

[Fred Fish]

Gcc generates some empty sections with special names as hints to
the debugger.  Newer binutils strips these by default.  This patch
keeps them.

	* emulparams/elf32bmip.sh (OTHER_SECTIONS): Keep the
	gcc_compiled_longXX sections generated by mips gcc.

OK.  I'd been meaning to do this for ages.

Could you add keeps for the ABI sections too?
        case ABI_32:   abi_string = "abi32"; break;
        case ABI_N32:  abi_string = "abiN32"; break;
        case ABI_64:   abi_string = "abi64"; break;
        case ABI_O64:  abi_string = "abiO64"; break;
        case ABI_EABI: abi_string = TARGET_64BIT ? "eabi64" : "eabi32"; break;

      fprintf (asm_out_file, "\t.section .mdebug.%s\n", abi_string);
