Frank Heimes 6fc450f696 (genprotimg|zipl)/boot: discard .note.package ELF section to save memory
The .note.package [1] section is not used by the zipl/genprotimg bootloaders,
therefore discard them via linker script.

This fix solves the error:
 /usr/bin/ld: Heap section doesn't conform to the described memory layout
 collect2: error: ld returned 1 exit status
 make[4]: *** [Makefile:77: stage3a.elf] Error 1
 make[4]: Leaving directory '/<>/genprotimg/boot'
 make[3]: *** [Makefile:20: all-recursive] Error 1
 make[3]: Leaving directory '/<>/genprotimg'
 make[2]: *** [Makefile:56: genprotimg] Error 2

Mikhail Zaslonko 4905975f81 zipl/boot: Adjust Makefile, loaders layout and a linker script
Use a separate linker script eckd2dump_sv.lds for single volume dumper with
compression support.

The new dump tool with zlib compression support now has a size of 8 pages.
Since DASD stand alone dump requires a block size of 4K, we are not
affected by the stage 2 size limitations and can load the dumper to
stage 2 as before. We just need to move the HEAP section for ECKD dumper
in the layout definitions up to 0xb000 address. Also expand the stack by
unused 0x400 bytes.
