Mike Frysinger 109a0a7e90 sim: modules.c: fix generation after recent refactors
Add explicit arch-specific modules.c rules to keep the build from
generating an incorrect common/modules.c.  Otherwise the pattern
rules would cascade such that it'd look for $arch/modules.o which
turned into common/modules.c which triggered the gen rule.

My local testing of this code didn't catch this bug because of how
Automake manages .Po (dependency files) in incremental builds -- it
was adding extra rules that override the pattern rules which caused
the build to generate correct modules.c files.  But when building
from a cold cache, the pattern rules would force common/modules.c to
be used leading to crashes at runtime.

## We must use 32-bit addresses to support memory bank switching.
## The WORD_BITSIZE is normally 16 but must be switched (temporarily)
## to 32 to avoid a bug in the sim-common which uses 'unsigned_word'
## instead of 'address_word' in some places (the result is a truncation
## of the 32-bit address to 16-bit; and this breaks the simulator).
