Drop --whole-archive and static libraries
Juan has contributed a cool Makefile infrastructure that enables us to drop
static libraries completely:
Move shared obj-y definitions to Makefile.objs, prefixed {common-,hw-,user-},
and link those object files directly into the executables.
Replace HWLIB by HWDIR, specifying only the directory.
Drop --whole-archive and ARLIBS in Makefiles and configure.
Drop GENERATED_HEADERS dependency in rules.mak, since this rebuilds all
common objects after generating a target-specific header; add dependency
rules to Makefile and Makefile.target instead.
v2:
- Don't try to include /config.mak for user emulators
- Changes to user object paths ("Quickfix for libuser.a drop") were obsoleted
by "user_only: compile everything with -fpie" (Kirill A. Shutemov)
v3:
- Fix dependency modelling for tools
- Remove comment on GENERATED_HEADERS obsoleted by this patch
