Really make WITHOUT_FORTH (MK_FORTH==no) work. The recent inclusion of
FICL definitions not in ficl/ficl32 files broke this generally. This
makes that stuff conditional on BOOT_FORTH. Also, move definitions
related to the architecture (FICL_CPUARCH and friends) into
Makefile.ficl that all parts of the tree that include files with ficl
need to include (but only if MK_FORTH == yes). In addition, had to fix
library ordering issue with LIBSTAND to keep it last. Without boot
forth, there's no references to memset to bring in memset.o from
libstand.a to satisfy libgeliboot.a's use of it. Listing libstand last
solves this issue (and it's the proper place for libstand to boot).
