- move guts of distrib/Makefile.inc to distrib/common/Makefile.distrib
(fixes problem caused by implicit include of ../Makefile.inc in certain
submake conditions triggered by makefiles not yet in tree)
- removed mkdir of ${RELEASEDIR}/*; rely upon "snap_pre" target of
etc/Makefile to create all the release directories
- renamed RELINSTALL to RELEASE_INSTALL
- renamed FLOPPYINSTDIR to FLOPPY_RELEASEDIR
- renamed MDSETDIR to MDSET_RELEASEDIR
- removed ITARGET
- move release target from top level to appropriate subdirectory
- ensure release target has correct depends
- replace miniroot's IMAGE_MD_POST with common/Makefile.image IMAGEPOSTBUILD
- Makefile.image: add realall: ${IMAGE}
symbols into locals, but relocs are left in place (rather than attempting
to resolve-in-place with "ld -r", even with "-Bsymbolic").
Standard MIPS code will generate CALL16 relocs for function calls, but
the linker forbids such relocs from being used to call local symbols (such
as those turned "local" by objcopy). So, rather than battle the toolchain
uphill, work around it for the moment by forcing 32-bit GOT references with
the assembler option "-xgot".
This will be fixed in a more clean manner in the future.
